There is no universe, neither real nor imagined, where the statement "the rest of the world is moving on from standard [fiat] money" does now or will forseeably parse as true.

I imagine that the pitch for Tesla includes some answer to “who cares?” quite easily. People who want to reduce emissions is a pretty big audience right now.

What are they moving to? Where is the data or transaction volume to support that the rest of the world except the US and EU are moving to alternative money?
