An essay in seven short parts

On Scarcity

What does it mean for something to be hard to make more of? Two answers, one inherited from the ground and one composed by rule, and what a careful reader might do with both.

Reading time: a few minutes.

The word we lean on

We use scarcity as if it were a single property, like weight. It is not. When someone says gold is scarce, and when someone says bitcoin is scarce, they are describing two different disciplines applied to two different kinds of thing. Scarcity is a relation among how much of something exists, how hard it is to make more, and how many people want it. Only the first two belong to the object. The third belongs to us.

It helps to pull them apart early. Supply scarcity asks how much exists and whether that number can grow. Cost scarcity asks what it takes to grow it. Access scarcity asks who can actually obtain it, and on what terms. An asset can be strong on one and ordinary on another, and most arguments about gold and bitcoin are quiet disagreements about which of these matters most.

Scarcity by geology

Gold was made long before anyone could count it. What sits above ground is the accumulated result of centuries of digging, melting, trading and hiding. What remains below is uncertain, and the effort needed to reach it tends to rise as the easier places are worked out.

This is scarcity of the stubborn kind. No announcement can add an ounce. Yet it is not a hard cap. Mines open and close, techniques change what counts as reachable, and the total keeps growing slowly, by an amount that people estimate rather than know. Gold’s scarcity is a slope, not a wall: expensive to climb, never strictly impossible. Its security comes from cost, and cost can be read in the price of fuel, labour and permission.

There is also the matter of what gold is. It is an element, number seventy-nine. It does not rust or tarnish in ordinary air, it can be melted and recast without losing its identity, and that continuity gives it a kind of memory. The coin and the bar are the same material at different moments.

Scarcity by rule

Bitcoin begins from the opposite end. Its limit is a number written into software: twenty-one million units, no more. A paper published in 2008 described the mechanism, and the first block, the genesis block, appeared in January 2009. Since then the network has issued new units as rewards for blocks, aiming for one block about every ten minutes, with the reward halving every 210,000 blocks, which at that pace is roughly every four years.

Miners spend computation on SHA-256 hashing to propose blocks, and nodes check each proposal against the rules. Ownership is tracked as unspent transaction outputs, each of which is either spent or not, and a spent output cannot be spent again. A block that tried to issue more than the rules allow would be refused by every node that checks.

This is a different kind of wall. It does not depend on geology and it does not tire. It depends on a very large number of people running the same rules and declining to run different ones. That is what makes it strong, and it is also what makes it a social fact as much as a mathematical one. Rules can in principle be changed if enough participants agree to change them. The resistance to doing so is the real guarantee. An honest reader holds both thoughts: the cap is exact, and the cap is kept.

A slope that is expensive to climb, and a wall that stands only while people agree to keep building it.

What you can check

Scarcity is only as good as your ability to confirm it. With gold, confirmation is physical and local: weigh it, measure its density, test it, have it assayed. Each test narrows the doubt and none removes it for free. For a large bar, most people rely on a refiner’s mark and the chain of hands behind it. Trust is spread across institutions and instruments.

With bitcoin, confirmation is computational and global. A full node can verify every rule from the first block to the latest without asking anyone. In principle that is a stronger kind of check, since it is complete and cheap to repeat. In practice it asks for technical effort, and most people lean on software or services written by others. The ideal of verification and the habit of verification are different things, for either asset.

The weight of keeping

To own something scarce is to inherit the problem of keeping it. A gold holder worries about fire, theft, and the person who knows where it is buried. A bitcoin holder worries about the same kinds of thing, translated: a device that fails, a backup that was never made, a phrase written down once and then mislaid. Metal can sit in a drawer for decades without anyone’s help. A lost key takes the value with it, and there is nobody to appeal to.

So durability has two faces. The metal’s is material and old. The ledger’s is procedural and young: it holds for as long as the software, the keys and the network of people holding to the same rules remain. Neither claim is hollow. They are different kinds of promise, and the length of the record behind each is very different.

Scarcity is not a price

A fixed supply says how much there can be. It says nothing about what anyone will pay. Plenty of scarce things are worthless because nobody wants them, and plenty of abundant things are dear because everybody does. The ratio on this site’s balance, ounces of gold per bitcoin, is only a relation between two prices that you type in. It is a snapshot of how two groups of buyers, at one moment, valued two different units. It does not predict and it does not recommend.

Be wary of anyone who treats scarcity as a destination. It is one input among several. Demand, usefulness, trust, legal treatment and the cost of holding all enter the picture. The scorecard tries to make that plain by letting you weigh the properties yourself instead of handing you a winner.

A balance, not a verdict

The beam at the top of every page is a reminder of the form this comparison should take. A balance does not tell you which of two things is better. It tells you how they compare against one standard, here and now, and leaves the choosing to you. Set the weights by what you value: portability if you travel, durability if you wait, verifiability if you doubt, predictability if you plan. People will honestly differ.

Gold and bitcoin are not rivals in any sense this page needs to settle. One is scarcity inherited from the earth. The other is scarcity composed by people and kept by habit. Reading them together is useful because each makes the other’s assumptions visible. Where gold asks you to trust matter and custody, bitcoin asks you to trust rules and keys. The thoughtful reader weighs the kind of trust each one asks for, and decides where their own caution lies.

Reading, not advice

This essay makes no forecast and offers no recommendation. It states a handful of long-established facts about the two assets, and the rest is argument you are free to reject. If you want to test it against your own numbers, the balance and the scorecard are one click away.
