The ability to increase/decrease money supply to counter various shocks is, in my view, valuable.
LOL, of course it's valuable. That's why elite families have worked on getting it for so long. Three US presidents have been assassinated over it.
If you actually support the monetary theory where a central authority can just mess with the money supply, then I doubt there is any purpose in debating the issue with you. If government needs to stimulate the economy, it should do so from tax surplus savings.
As for your comment on Zimbabwe, you obviously missed my point. Its currency is deemed worthless, so the people decide for themselves at the markets. That's how a medium of exchange comes about, from the people and the markets.
