Yikes, that is a lot of power. Been an ideological Bitcoin holder/gold bug/physical cash fan for quite some time now. The sophisticated mechanisms that Central Banks have to control the economy/money seems dangerous in shortsighted democracies, and nightmarish in more authoritarian states.
No anonymity in financial transactions makes it easier to catch drug dealers and tax evaders. The ability to control the money supply will keep the economy healthy (theoretically). Only problem is the ability of communities/individuals to economically resist national governments is so thoroughly squashed that citizens are turned into subjects when the nations elites decide subjugation is a good idea.
Dirty secret of politics is that rights become inalienable in the same way boxers become champions. By winning a lot of fights.
