There will indeed always be taxes and tax collectors. But to conclude then that there must be an IRS is bogus man.
The obvious contradiction is state sales taxes. There a tax and there are tax collectors - but no IRS.
The method of tax collection matters greatly wrt freedom.
We need to end the Federal government’s independent tax collection completely, except for modest tariffs. Individual states should be billed for their share of federal spending, and the states should figure out how to collect it.

Actually there is a state equivalent. That would be in Tennessee the Department of Revenue. Individuals have little interaction with them, but businesses do. They receive the taxes and come after you if they suspect non payment.
If you are a Rush listener, you would know that the entity in NYC harasses him constantly even though he lives in Florida. They audit him every year even though it has been many years since he lived or worked in NYC
I stand by my statement. If the IRS has a name change, the new entity will still need to enforce what ever tax code comes about.
