That seems to me how it would play out, too. The counter-argument I can imagine is that the only way that a country in the modern world could get on a btc / hard money standard again would be if all the other countries also were. Put differently, maybe "all else equal" is not a reasonable axiom to assume, even for a thought experiment.

But the burden of proof -- or of really convincing argumentation -- needs to be on the people talking about a reality other than the one we're in now.
