Won't happen. International banks won't allow it.
It has nothing to do with what governments want.
It has everything to do with the power derived behind the current debt-based monetary system.
If other countries moved toward a non-debt money supply then I would be their biggest cheerleader. Crypto isn't it...
I'm talking about each country's Treasury being the issuer of their respective money supply - not backed by the bonds issued by the country, but by the faith and trust of the Treasury.
A hot economy could be cooled by taxing more and destroying the money coming in to lower the amount available.
A cool economy could be stimulated through the creation of public-works projects that would then be spent into the economy through purchase velocity.
Of course, this means that money could only be injected into the economy through the completion of labor (public works, etc) - so would have a natural cap on it that couldn't be exceeded.
Banksters don't want this - they want debt-based money so they can control the future labor (future actions) of others - which is also known as "power".
Power is what this whole charade is all about...
Time will tell
Debt free fiat currency system. I like it! Too bad it will never happen unless the current system falls apart.
