You are right. My point is that if you have international trade of even mild complexity, having a currency is very convenient so trade will end up being denominated in one. No reason it can't be some crypto that is not backed by any nation.

There is a great reason: a state-backed currency should always be accepted by that state. If the world is in crisis, you may wind up stuck with your Bitcoins.
