>"Sure, and Euros are also backed by the EU economy. The point is 'national' currency's are actually backed up by enforced demand unlike say Ethereum"

I agree with this but that's also the main differentiator is that the "legal tender" of a country backed up by enforced demand while Bitcoin and backed up purely by supply and demand. I think I misunderstood your point with regards to the tax examples.

However I don't agree that inflation can not be controlled exclusively through taxes. That is but one component the much bigger lever being the monetary policy of the central bank.

I am more talking about the long term. Total value of all currency is going to be +/- some % * k of GDP so over say 100 years you get minimal average inflation or deflation and the average keeps dropping as you increase to say 200 years etc.

But, even if it's value is stable in the long term that's arguably less important than month to month and year to year stability because you need to make loan payments today or buy food today etc.
