I think it's fascinating that this is 100% different than what Bitcoin was sold as. The theory of Bitcoin was basically "money without people". You wouldn't have to worry about governments and politics; value would be sent and stored in pure pieces of math.

The problem here is not Bitcoin per se, it is the current state of the real world, where anyone can "buy" and "sell" Bitcoin for legal tender. Bitcoin, in a world where it is the sole currency, has the benefits you quoted.
If Bitcoin doesn't work in the real world, that's a problem of Bitcoin.

If Bitcoin doesn't offer sufficient benefits in the real world as it is without being the sole currency in the world, there's no plausible route to it becoming the sole currency.
