People used money - tokens of currency exchange - long before there were centralized states.

People in the US became far more accepting of a centrally controlled money source after the Panic of 1837. One of the many causes of this crash was that banks were issuing their own money in a fraudulent or in an insecure manner.

This became the de facto authorization of a central bank and a central money, despite the fact that it wasn't really necessary.

Just remember that any currency depends on market value, AKA trust.

These days, I would put more trust in the blockchain than the politicians that control the Fed.

And please do write more on this, it is an excellent subject!
