I m confronted to someone who states that Satoshi Nakamoto never compared Bitcoin to gold in the monnetary sense (not about mining).
However, I m sure to recall a quote from Satoshi stating Bitcoin is digital gold which was used several years ago in the debate of Bitcoin vs Bitcoin cash as an argument that Bitcoin is a store of value and not a meant of payment.
I m failing to find it again. The only thing I found is about Bitcoin mining, but this isn t in the meaning I need to prove.

The Money Regression and Emergence of Money from the Barter Economy
The entire purpose of the regression theorem was to help explain an apparent paradox of money: how does money have value as a medium of exchange if it is valued because it serves as a medium of exchange? Menger and Mises helped break this apparent circularity by explaining the essential time component missing from the phrasing of the paradox.

As Rothbard explains in Man, Economy, and State (p 270),
"...a money price at the end of day X is determined by the marginal utilities of money and the good as they existed at the beginning of day X. But the marginal utility of money is based, as we have seen above, on a previously existing array of money prices. Money is demanded and considered useful because of its already existing money prices. Therefore, the price of a good on day X is determined by the marginal utility of the good on day X and the marginal utility of money on day X, which last in turn depends on the prices of goods on day X 1. The economic analysis of money prices is therefore not circular. If prices today depend on the marginal utility of money today, the latter is dependent on money prices yesterday." [all emphasis added]

Rothbard then goes on to explain that in order for money to emerge from a barter economy, it must have a preexisting commodity value. This commodity value arises from barter demand for the potential money in direct consumption (i.e. ornamentation). This value seeds future estimations of the value of the money as a medium of exchange. The natural market emergence of money is thus fully explained.

The Monetary Economy
However, once an economy has been monetized and a memory of price ratios for goods and services has been established, a money may lose its direct commodity value and still be used as a money (medium of indirect exchange). Rothbard explains (p 275):
"On the other hand, it does not follow from this analysis that if an extant money were to lose its direct uses, it could no longer be used as money. Thus, if gold, after being established as money, were suddenly to lose its value in ornaments or industrial uses, it would not necessarily lose its character as a money. Once a medium of exchange has been established as a money, money prices continue to be set. If on day X gold loses its direct uses, there will still be previously existing money prices that had been established on day X 1, and these prices form the basis for the marginal utility of gold on day X. Similarly, the money prices thereby determined on day X form the basis for the marginal utility of money on day X + 1. From X on, gold could be demanded for its exchange value alone, and not at all for its direct use. Therefore, while it is absolutely necessary that a money originate as a commodity with direct uses, it is not absolutely necessary that the direct uses continue after the money has been established."

This explains the history of fiat currencies. They originally started off as simple names for weights of commodity money (silver) that developed out of the pre-monetary barter economy. Despite later losing their ties to direct commodity value through state interference, paper currency retained status as money because of memory of previous money prices. This factor is so strong that the relationship between gold and the USD, for example, is somewhat inverted. Gold no longer circulates as a common medium of exchange. Prices are set in USD, not in gold. Most individuals wishing to trade in gold do so based on their knowledge of USD/gold price ratios. ("Hey, let me buy that $100 couch from you in gold?" "Ok, USD/gold is $1000/oz. Give me 1/10oz of gold.") Legal tender laws, state taxation, and the entire financial regulatory environment maintain this inertia of USD prices and make it challenging to return to gold money directly, despite the destructive inflationary nature of fiat currencies.

As a thought experiment, imagine there was a base metal as scarce as gold but with the following properties:
- boring grey in colour
- not a good conductor of electricity
- not particularly strong, but not ductile or easily malleable either
- not useful for any practical or ornamental purpose

and one special, magical property:
- can be transported over a communications channel

If it somehow acquired any value at all for whatever reason, then anyone wanting to transfer wealth over a long distance could buy some, transmit it, and have the recipient sell it.

Maybe it could get an initial value circularly as you've suggested, by people foreseeing its potential usefulness for exchange. (I would definitely want some) Maybe collectors, any random reason could spark it.

I think the traditional qualifications for money were written with the assumption that there are so many competing objects in the world that are scarce, an object with the automatic bootstrap of intrinsic value will surely win out over those without intrinsic value. But if there were nothing in the world with intrinsic value that could be used as money, only scarce but no intrinsic value, I think people would still take up something.

(I'm using the word scarce here to only mean limited potential supply)

Not exactly what I want. Though in the same vein. I remember it was specifically with gold.
