If you've got the dough to throw down there are lots of properties out there far from humanity surrounded by complete wilderness. If you mind yourself and don't involve yourself in other people's business, and scope out the locals before moving, you should be able to live peacefully for years without anyone bothering you. Provided you don't mind the occasional intruder. After a decade or so of not paying taxes you berry well may have to contend with the cops or glowies.
You could also find a nice cave somewhere and live like a nomad. Constantly moving from place to place in heavily wooded areas. To avoid detection for as long as possible you can make yourself some anti-x provisions like an anti-heat-detector coat using a coat and sewing in some space blankets.
If you live in the US you could also squat in large national parks. Despite what the government wood have you believe many of these parks are thousands if not millions of acres. You could comfortably squat for years and evade detection. After that there is not promises however much like my first suggestion.
You could also become a hermit in a car. Much like living in caves do the absolute bare minimum of leaving your car and live in it the rest of the time. Buy a generator or hook up to your car battery if you want electricity for whatever.
Or you could always turn to drugs and pretend you're alone.
