That was not my argument at all. First I said, I don't see bitcoin as currency at all. Second, major nation states have always tryed to use their power to force other nations to use their currency (petrodollar, cough). This is nothing specific to crypto, but something also specific to traditional fiat currencies.

Any high-volatile asset such as bitcoin is IMHO not suited as currency. The good news is, with the bitcoin taproot upgrade and latest lightning standards, you can actually issue stablecoins over bitcoin's taproot asset protocol, and send it over the existing lightning network. My bet is on stablecoins-over-lightning as currency, and bitcoin as store of value. One blockchain to rule them all, other chains not need (for financial transactions at least).
