I have heard that China is very nationalistic…nationalism isn’t just for White guys with little black mustaches.
besides, we already have a unified global monetary policy based on the USD. Why do you think a similar replacement with a different name will be acceptable now that it is clear that its predecessor has failed? When Fiat money dies it is never immediately replaced with a new confidence game Fiat. Failed Fiat is always replaced with something with physical collateral backing.
