I’m not aware of any other digital transaction methods that can send un-printable money besides cryptos.
I think devaluing currency to inflate stocks and fund wars is harmful, and cryptos are a valuable solution. Although, I think there’s better than PoW.
That's because it's not a useful feature heh. Money is meant to be a medium of exchange and temporary store of value. To the extent it holds its value for the duration of your ownership of it, it's met its goal.

> Even if you convince the US government to switch to BTC
There's no need for that. It would be enough for some people to switch to BTC. I.e., not store their money or denominate their salaries in USD.
As things stand, most wealthy people already store their money in things other than USD that are somewhat less easy to manipulate, like stocks and commodities. It would be nice if this strategy were more accessible to people worldwide.
This is the broken window fallacy writ large. The small value cryptocurrencies provide over other digital transaction methods is overshadowed by the huge inefficiencies of how transactions are processed via PoW. The fact that there are companies that have made a fortune dealing with all these "broken windows" doesn't change the basic fact that cryptocurrency is probably the least energy efficient way to move money digitally.
