means of exchange
Who said anything about using BTC as Medium of Exchange? Only net demand carries novel state information, so all relevant information can be encoded into bitcoin via aggregate demand for “economic unit”, MoE use does not increase the fidelity of the price signal so is wholly superfluous. You use Bitcoin by buying, selling or transferring it, not by trading it for coffee.
Economy is based on trust
False. Economy is based on The Positive Externality of Voluntary Exchange, economic abstractions like money evolved because without such abstractions the complexity of economic interactions is limited by the parabolic growth of prices as the economy becomes more complex (n^n prices without a money, n prices with a money).
earliest monies
Were commodities like grain, salt. These work fine as a MoE (as there is little term risk in MoE) but can’t function as an abstract economic unit as increases in demand for said commodity will increase the amount not price of the commodity as these have great elastic supply. This is why gold was gained market share for this function, because it has less elastic supply than the vast majority of commodities.
Notice that gold is trustless (in physical form), yet “despite” this (because of this) the greatest periods of prosperity throughout history have been under gold-money. Bitcoin goes beyond gold, trustless, intangible, perfectly inelastic supply. Not only will NSAs be unable to corrupt the Trusted Third Party of Bitcoin (for there is none), but they will also be unable to mass seize bitcoin as BTC is intangible. This is a literally priceless.
