The logic is impenetrable. Ask a Statist where money comes from. Chances are, they won’t know.
If it’s counterfeiting for anyone but government agents to create dollars, then they can’t possibly need tax dollars to fund programs (revenue)—they can always print.
Taxation must have some other purpose. That purpose is to imbue the otherwise worthless currency with value as get-out-of-tax-jail coupons.
Fiat currency, because of taxation, is a tool of oppression whereby the State extracts labor from its captive subjects.
