If they are adding money into the economy and charging taxes then it is double taxation
I agree, but I don't think that's bad by itself. To me it doesn't matter if taxes are collected via inflation, a wage tax, or both, what matters to me are these two things:
(1) The taxpayer was robbed if the government charged him more than his share of the government's total costs (including reasonable salaries for government employees).
(2) And he was also robbed if the government intentionally spent higher-than-reasonable amounts of money so as to hike up the taxpayer's share and make him pay a higher-than-reasonable amount too.
If a government would just avoid both of those pitfalls then I wouldn't mind if they used inflation and a wage tax to collect value from taxpayers. To me, either method is fine as long as the government's expenses are reasonable and they collect the same share from each taxpayer to cover those expenses.
Fact is that there are taxes and arbitrage is helpful
Agreed
