Though extremely difficult, it's possible to exist in the USA without paying any tax to any entity.

You would have to be unemployed, receive food and water through non-sales-tax-included methods (like living in New Hampshire or going to a local soup kitchen or boiling grass), and never own a home or rent even.

Well come to think of it, you could probably eat sleep and drink at a casino all day, if it's on native land.

Yeah, but why? That sounds awful

I mean, that's why I said it would be extremely difficult. This is a thought experiment, similar to thinking about what happens when you cross the event horizon-- death obviously, but other interesting things too.

yeah but you're still paying for a service from a provider which pays tax to the government

No, I literally described situations where nobody is paying taxes. Most shops in NH and non-profits don't make enough revenue to pay taxes on it.

And native american land by it's definition is not taxed.
