I don't really know either. Maybe you're right, but as a (maybe ridiculous) counterpoint, what benefit does it give a government to have their own currency? I think the main benefit is not having to rely on another government to keep it stable... or to avoid the subservience that follows from having to rely on acquiring said currency from another government. For most countries now practically I think this means 'not giving the US complete control over our politics and not having to buy USD from them'.

Are there any other benefits? If not, wouldn't adopting bitcoin be an easy solution to monetary policy while avoiding this issue? Or am I missing something?
