But this problem always poses itself. How does a country know a central bank abroad will give it back its gold? (sometimes it won't, ask the British where Venezuela's gold is.) Who makes sure the treasury pays the countries' bills? /sometimes it won't,. as happens in the US every few years when the showmanship circus of the debt ceiling comes up). Those are "bureaucratic multisig", as in, a number of civil servants with the authority to decide this are involved in making this happen. "The government", in the end, is also people. But definitely better having people in your OWN organization hold keys than giving it over to a corporation abroad. Especially in the US, and especially when the same US has been making a stink about the bitcoin legal tender law and is discovering lots of need for "more democracy" in ElSal. This is foolish.
