Earlier quoted context omitted.
All of your post assumes that when government creates money, it causes inflation, and when private banks create money, it causes no inflation. No such distinction exists. Most money is created by private banks.
I know most money is created by private banks. But that is stable (it is assumed by ceteris paribus). If a government decided to stop taxing then that would be something new.
Private banks used to be able to print their own currency completely: in one country each bank would have different money that coupd be redeemed for gold, and wasn't backed by the government. That was very unstable.
We basically stopped taxing multinationals after the end of cold war, we do have something new.
