Glad that you are one of the few people who also get why the gov is always so concerned with taxes when they can theoretically print money with ease. Taxes are the money sinks that fight inflation which is why I consider MMT the full power of fiat.
Inflations hurt their power to print hence taxes for the fed gov.
State/local gov taxes make a bit more sense on tax fights as they don't have the money printer but at least those are a bit more controllable(Easier/move away from type things).
