I think he would make fractional reserve illegal and criminal. This would create a lot of stability and security which means a much better place to leave your dollars than any other place on earth, if you're a boomer and can't use sats of course.

Well ok. Could be the case to attract some dollars from abroad. Still more wishful thinking than anything else. The situation in Argentina was very fluid to suddenly gain such trust, while Miley himself doesn't seem very "stable".
And what about the sudden 100% reserve ratio? How can this happen?
