One goverment you have to pay taxes to in order to stay out of jail and don't get to make any real choices about how much money it prints out of thin air..

The other is an organization body that you freely choose to associate with, eg: using Etherium.

I don't understand how you can conflate the two.

Vitalik did not print billions of dollars out of thin air and then force every citizen of the US to bear that cost through the inflation of the US dollar eating away at their savings and investments.

I don't make any choices about how much money Ethereum prints out of thin air, who it prints it to, or how much the transaction fees are.
