If you work in the 'normal' world and live super cheap, you can save up enough money for remote land. Then you would own it and no one could kick you off. It would be really sad to be kicked off after several years work. Once you squat, you may not be able to generate enough money to ever buy the land or the owner might not be willing to
sell it. I don't know the issues of squatting on Fed land, but if you squatted on MY land, you'd be dealing with one pissed off fellow.
The other issue is that you can get hurt. How do you get help? I played sports in high school and college and am very coordinated. In my construction career, I have broken my hand, broken my upper jaw with the loss of two teeth (that was a bloody one), hurt my back (badly) and got a piece of steel in my eye (sticking in the the eye ball). Access to medical help is important for illness also.
I live near a small rural town now and even in town there aren't enough doctors.
I don't mean to poo poo your idea, just to point out some issues. Good Luck what ever you choose to do!
