> Controlling your money supply can be needed to improve your country's position with regard to foreign trade. This is basically protectionism, an economic theory that has been debunked time after time. If it were true, then why doesn't it hold true for individual states within a country? And while we are at it, why not a currency for every city or neighborhood? > Because people still need to be able to transact with something, which is not a function well-served by cryptocurrencies, most of which have the bulk of trade in them carried on off-chain or via stablecoins that track a fiat currency. Those same systems could simply add support for cryptocurrency. Paypal did a few months ago (not sure if they enabled merchant support or p2p transfers, but there's no technical barrier preventing them to do so). Credit cards could also add crypto to the long list of currencies they already support. Etc.
