I think the time for gold panning is long past. As for squatting, the best way would be to not disturb the land so as to make your presence noticed, and to continually move from place to place while also avoiding infrastructure.

The solution isn't a cabin in the woods. The important thing is sovereignty and that's a hard thing to get when all of the land has been claimed. You don't have to do something that drastic. There are many towns with only 200-300 people that you and people aligned with you could have control over. No need for the running from rangers stuff unless that's a kink you have.
