letter 6 – the physics of value

in a world where AI is driving the cost of digital creation toward zero, where does scarcity — and therefore lasting value — actually live?

 

Dear friends,

One of the hardest lessons I’ve had to learn — and keep relearning — is that money and value are not the same thing.

Money is elastic. It stretches and contracts with policy, sentiment, and politics. In one era it buys a farm; in another, only a car. It can be printed, diluted, or redirected with a keystroke.

Value behaves differently. Value responds to gravity.

It flows toward what the world truly needs and away from what it doesn’t. You can’t always model it, but you can feel it — like a quiet force pulling capital toward necessity over time. Once I began seeing investing through that lens, the noise receded and something steadier came into view.

Necessity as an Anchor

Over the years, I’ve found myself asking slower, simpler questions about investments.

Not just What is the growth trajectory? Not just What is the exit multiple? Not just Who else is in the deal? Those questions have their place. But I’ve noticed that the investments I feel most settled about — the ones I can hold through volatility without second-guessing myself at 3 in the morning — are the ones that pass a different set of tests entirely.

Does this meet a basic human need? Is it difficult to replace? Can it remain useful across changing conditions — different administrations, different interest rate environments, different technological eras?

Those questions keep pulling me back to assets that underpin daily life rather than disrupting it.

The apartment that shelters a young family who can’t yet afford to buy, or a retired teacher who has downsized and wants simplicity. The warehouse that moves the goods people ordered online without ever thinking about where those goods spent the night before arriving at their door. The storage unit that holds the remnants of a life in transition — a divorce, a move, a death in the family, a business that needed somewhere to put its inventory while it figured out its next chapter. The shopping center is anchored by a grocery store and a pharmacy where people show up not because they chose to but because they need to — week after week, year after year, regardless of what the market did yesterday.

None of these things are clever. None of them will ever be the subject of a breathless pitch at a technology conference. Nobody is going to write a magazine profile about the profound innovation of a loading dock 

But they are necessary. Quietly, stubbornly, persistently necessary.

And that necessity — when you really sit with it — turns out to be one of the most durable forces in investing. Because necessity doesn’t follow sentiment. It doesn’t care about the news cycle. It doesn’t pause during corrections or accelerate during manias. It just continues. People need somewhere to live. Goods need somewhere to move through. Lives need somewhere to put the things that don’t fit in the current chapter. Communities need places to convene around basic functions.

That was true in 1990. It was true in 2008. It was true during COVID when almost everything else stopped. And it will be true in 2045 regardless of what the Fed does or which political party controls the House.

Longevity makes that necessity more powerful still.

Over a shorter financial life, you can afford to chase cycles — to ride a trend, capture a return, and move on before the fundamentals reassert themselves. Over a longer one, the fundamentals are almost all that matter. Because across forty or fifty years of active financial life, you will live through enough disruptions, regime changes, and technological revolutions to see every clever thing eventually become obsolete.

What doesn’t become obsolete is the apartment. The warehouse. The storage unit. The grocery-anchored center. The physical infrastructure of ordinary life.

Demand for these things doesn’t just persist across a long life. It compounds. The population grows. The cities densify. The supply of well-located physical infrastructure stays stubbornly constrained even as the number of people who need it keeps rising. And the money supply — as we’ve explored throughout these letters — keeps expanding faster than the real economy can absorb it, pushing an ever-larger pool of capital toward an ever-more-limited stock of necessary physical assets.

Financial longevity emerges not from speed or novelty, but from proximity to what people cannot do without.

That sounds almost too simple. I’ve found, over twenty years, that the things that sound too simple are often the ones most worth sitting with.

Scarcity Multiplies Value

If necessity anchors value, scarcity multiplies it.

When something is both essential and limited, value naturally pools there. You can see it in housing constrained by zoning, in ports that can’t expand, in water rights that sustain entire regions. The more abundant our digital world becomes, the more precious the finite grows.

Longevity sharpens this effect. Scarcity compounds not just annually, but generationally.

Consider a well-located self-storage facility in an infill urban market. The land it sits on cannot be replicated — the city has grown around it, zoning has locked in its use, and the cost of assembling comparable land nearby has become prohibitive. Twenty years ago it served people moving between apartments. Today it serves those same people — now older, downsizing, managing aging parents’ belongings, storing the inventory of small businesses that can’t afford warehouse space. The demand has not just continued. It has deepened and diversified across multiple phases of life.

Meanwhile the replacement cost of that facility has roughly doubled. The land value has climbed faster still. And the number of people whose lives intersect with that building — who need what it offers at some point in their arc — has grown with the population around it.

Nothing about the building changed. Time changed everything around it.

And so did the money supply.

While that facility was quietly doing its job — storing furniture, business inventory, the accumulated evidence of lives in motion — the number of dollars in the system roughly tripled. The broad money supply went from $7.6 trillion in 2008 to over $22 trillion today. Every one of those additional dollars needed somewhere to go. Some went into stocks. Some into bonds. Some into consumer prices. And a growing portion went looking for something real — something finite, something useful, something that couldn’t be conjured with a keystroke.

That facility didn’t just benefit from time. It benefited from the tide.

Scarcity plus necessity plus an expanding pool of money searching for a physical home. That is the full equation. That is why a building that hasn’t changed in twenty years is worth dramatically more than it was — not because it became more impressive, but because the measuring stick used to price it kept getting longer.

This is what generational compounding of scarcity actually looks like in practice. It isn’t dramatic. It doesn’t announce itself. It just quietly becomes more true every year — harder to replicate, more embedded in the fabric of daily life, more necessary to more people across longer spans of time, and increasingly scarce relative to an ocean of liquidity looking for somewhere real to anchor.

What can’t be replicated becomes harder to access as time passes, while demand stretches across longer lives and the money supply stretches even faster.

This is where financial longevity quietly asserts itself: by aligning capital with assets that benefit from time rather than being eroded by it. Not assets that need to be right about the future. Assets that simply need the world to keep being the world — and the money supply to keep doing what it has done for the past twenty years without interruption.

The Digital Concentration Problem

At the same time, I can’t ignore where the global economy has tilted.

AI and platform technology have driven the cost of producing knowledge, design, and analysis toward zero. That abundance is extraordinary — but it also concentrates ownership. The real wealth of the digital economy is created in private deals, long before public participation is possible, and it accrues to a narrowing circle of insiders with access, scale, and patience.

It wasn’t always like this. For two or three decades during the rise of public tech, retail investors had a legitimate shot at transformational upside. You could buy Amazon, Google, or Nvidia at IPO — not at insider prices, but still at a human scale — and ride the compounding for years. The curve was steep but accessible. The story wasn’t fully written yet.

That window has narrowed considerably.

By the time a company like ChatGPT might debut at a trillion-dollar valuation, the question of whether it 50x’s from there becomes more about hope than probability. Size is the enemy of retail upside. By the time transformational companies reach public markets, most of the exponential curve has already been captured by the people who were in the room years earlier.

This doesn’t mean you should have no exposure to the AI economy. That would be its own mistake — and I want to be clear about that.

Broad index exposure to the technology sector — owning a slice of the whole field rather than betting on a specific winner — is a reasonable and sensible thing to hold. The AI economy will generate enormous aggregate wealth even if no individual investor can reliably predict which company captures the most of it. An index doesn’t require you to pick the winner. It just requires you to be present in the room.

The honest challenge is that picking individual AI winners at this stage requires either insider access, extraordinary luck, or a level of technical foresight that very few people genuinely possess. The venture world lives inside the part of the curve where the real upside concentrates. By the time most of us see the opportunity, much of that curve has already flattened.

So the practical question isn’t whether to participate in the AI economy at all. It’s how to participate honestly — with appropriate position sizing, realistic return expectations, and a clear-eyed understanding of where you actually sit in the information hierarchy.

For most people outside the venture ecosystem, that means broad exposure rather than concentrated bets. It means treating AI-related public equities the way you’d treat any other sector allocation — as one component of a diversified portfolio, not the centerpiece of a financial longevity strategy.

And it means recognizing something that the enthusiasm around AI tends to obscure: the companies building AI infrastructure — the data centers, the energy corridors, the logistics networks, the physical facilities that house the computers — are often more accessible, more tangible, and in some cases more durable than the AI companies themselves. The picks and shovels of this gold rush, like every rush before it, may ultimately prove to be more reliable compounders than the miners.

This means most people won’t own the algorithmic monopolies. They’ll experience them as users, tenants, or data points. But that doesn’t mean they can’t participate in the broader AI economy — it means they should participate thoughtfully, with realistic expectations, and without confusing exposure to a theme with ownership of the value it creates.

Longevity makes this distinction impossible to ignore. Over decades, concentration compounds just as surely as scarcity does. The gap between those who own digital rails and those who merely ride them widens quietly over time.

The Broad Doorway

But here is what that gap doesn’t mean.

It doesn’t mean the physical world is a consolation prize for people who missed the digital revolution. It means the physical world is a different door entirely — one that has always been open and remains open — to a form of ownership that doesn’t require perfect timing, insider access, or the ability to predict which algorithm wins.

For all its power, the digital economy offers narrow ownership. The physical world, while finite, offers shared access.

It’s difficult to privately own a platform monopoly. It’s still possible to co-own housing, logistics, energy, and land — to invest alongside others in assets that serve real needs, generate income, and can be improved through judgment and stewardship. These are assets where your value-add as an investor is not predicting the future correctly but simply being a capable, patient steward of something people already need.

You may never own a meaningful share of the next trillion-dollar AI model. But you can own the building its engineers live in, the warehouse its hardware moves through, or the land its servers sit on.

That isn’t settling. That isn’t giving up on the future.

That is financial longevity expressed in its most practical form — ownership that compounds quietly across decades, that doesn’t require you to be the smartest person in the room at exactly the right moment, that simply asks you to remain aligned with what the world continues to need regardless of which technology dominates any given era.

The practical response to the digital concentration problem isn’t to avoid the digital economy. It’s to own a diversified slice of it — broad index exposure, realistic sizing, no concentrated bets on specific winners — while anchoring the majority of your financial longevity strategy in the physical world that the digital economy cannot exist without.

The AI economy needs land. It needs energy. It needs buildings, logistics networks, and the physical infrastructure of human life. Every data center requires power. Every engineer requires housing. Every server requires cooling, maintenance, and the unglamorous physical systems that keep it running.

The digital world floats on the physical one.

And the physical world — finite, necessary, increasingly scarce relative to an expanding pool of capital looking for somewhere real to land — has a very long history of rewarding the patient, the grounded, and the unhurried.

That is the broad doorway. And unlike the narrow entrance to the venture world, it doesn’t require an invitation.

Time Reveals What Endures

In the physics of value, time is the final force.

Not interest rates. Not policy cycles. Not the particular genius of any individual investor or the particular brilliance of any specific technology. Over a long enough horizon, time is what separates what merely appeared valuable from what actually was.

Over time, necessity and scarcity compound. The well-located building becomes harder to replace. The supply-constrained market becomes more supply-constrained. The asset that served a human need in 2005 serves a deeper, more diversified version of that same need in 2025 — and will serve a still deeper version in 2045, as the population ages, the money supply expands, and the number of people whose lives intersect with that asset grows.

Over time, speculation and excess decay. The narrative that justified an extraordinary valuation eventually meets the reality that couldn’t sustain it. The leverage that amplified the upside amplifies the downside on the way back. The transformation that was certain turns out to have been merely likely, or merely possible, or merely the dream of a particular moment that the market had already fully priced.

I’ve watched both of these forces work across two decades of investing. The compounding of necessity is quiet and almost invisible year to year. The decay of excess is dramatic and obvious in retrospect and almost always surprising in the moment. Time is what separates the two — and patience is what allows you to hold the first long enough to feel the difference.

The longer I’ve done this work, the more I’m drawn to building for duration. Not for the next cycle. Not for the next exit. For the long arc — assets and structures that can breathe through cycles, absorb shocks, adapt as conditions change, and still be doing their fundamental job twenty years from now without requiring anyone to have been extraordinarily right about anything.

My father understood this without ever having the vocabulary for it.

His money was fragile. Milk checks that fluctuated with every swing in commodity prices, every drought, every shift in what the co-op was paying that month. Cash in the front pocket of his shirt that passed through his hands almost as fast as it arrived. He didn’t accumulate wealth through his money. He accumulated it through his assets — the herd, the land, the barns, the equipment, the relationships with neighbors who would help bring in a harvest or lend a piece of machinery when something broke.

Those things didn’t fluctuate the way the milk check did. They aged differently. They absorbed decades of inflation, policy change, and economic turbulence without losing their fundamental usefulness. The cows still needed to eat. The land still produced. The barns still stood. And when my parents eventually converted some of that land and equity into commercial real estate, it was the same instinct — not speculation, not transformation, just the quiet confidence that what feeds, houses, and powers life tends to hold its value across time in ways that paper promises rarely do.

He never said any of this. He didn’t need to. He lived it every morning before sunrise, and the evidence was in the life it sustained.

I think about him often when I’m sitting across from a family trying to figure out how to build something that lasts — something that can carry them through the next thirty or forty years without requiring them to be right about everything. The instinct I’m trying to describe to them is the same instinct he had. It just requires different tools now, a broader vocabulary, and the willingness to apply an old truth to a new set of conditions.

Money measures the moment.

Value measures what endures.

In a world moving faster than it ever has — where symbols inflate daily, where liquidity expands structurally, where AI accelerates the pace of change in ways we are only beginning to understand — learning to tell the difference between those two things may be the most important investment decision any of us will ever make.

Not the cleverest. Not the most sophisticated. Not the one that requires the most data or the most precise timing.

Just the most important.

 

Warmly, 

Gino

P.S. In my next letter, I’ll share a lesson I learned the slow, humbling way — about liquidity, capital, and why cash and wealth are not the same thing.
