Yes, the US can still raise funds other ways. It would still be preferable if they were more transparent about it.

> 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.
