Quoted By:
Some regions have ways of paying your property taxes via a kind of reverse mortgage on the land itself. If you can find one of those locations, you may be able to secure a deal that effectively gives you ongoing land ownership with zero property tax, with the land reverting to the state upon your death. You have to have invested enough initial capital in the land to make it economical for them, though.
So that's the property bit, assuming you want dominion over the land. Living on property you don't own in buttfuck nowhere is a possibility, but the living is harder and you're at the mercy of ongoing luck to not get caught. The more remote you go that risk lowers, but the survival opportunities get worse as you head further out (i.e. trying to survive in a desert/arctic location rather than somewhere more habitable, where there are more people).
Everything else, sure you may be able to find ways of living without external inputs. But the biggest issue will come if you also want to eschew all dependencies on other people. What if you get sick? What if one year your food crops fail? Are you willing to forego all modern conveniences e.g. butter? Where are you going to get a cow? How will you replace that cow down the line?
There are lessons to be learned from others that have attempted to go it alone. The North Pond Hermit, for example. Couldn't survive without raiding people's cabins for supplies. There's also a book by Gerard Hindmarsh called 'Outsiders' which you might find interesting.
