As an example, I am against any system that takes us back to a world where governments no longer are able to use the soft power of economics to react to other countries. The alternative being that they will need to result to hard power which means physical violence.
The rest of the stuff like being a haven for criminals, grifters, and scam artists is related to but not really the cause for my bias.
Said like somebody who never had a problem with the financial system and had access to banks for their entire life. It's great that money works for you, for most people on this planet the same can not be said.

The idea that monetary policy is the only way to influence economics seems kind of absurd? You're surely not suggesting that removing fiat currencies would remove economics from the world of politics?
But I guess your bias is because you live within this system, right?
