I see absolutely no reason why not with the right combination of motivation, location, skill, charisma, brains, and plain good fortune. I don't believe it would necessarily involve living off the land though.
Consider the amount of illegal immigrants that go missing here. They demonstrate that even in a foreign land, and often with little or only a rudimentary grasp of the native language, some can get by through hiding in plain sight. Similarly, we have the so called traveling communities, bands of pikies with little or no contact outside their own, many of which would completely duck under the radar if they didn't draw state benefits. Charisma can often find safe harbor. And so on. People give themselves away with sloppy drills, atavism, and emotional states that triumph over the intellect's knowing that giving up everything means
everything right down to the smallest. For example; no more trees, or dogs, or Gortex, or nice knives, and learning to love Elvis and perhaps getting god and going muslim or something. No friends or relatives and especially the old favorite the egoist Google vanity search for the former self. All honey traps. Tabula Rasa.
That said, I don't believe all people start from the same point even if hypothetically they had the same amount of the ingredients I mentioned above. And it is getting worse. For many privacy is already dead and they just don't know it. Example; there's probably a few here that know an image search can be run by uploading a photo and a search will be made for photos similar to it, not by the name of the file but by what is contained in the image, but how many of you know about
Goggles. So, Google has dumped the idea, so what. The point is the technology is now so mundane it is ready for dissemination to plebs. This isn't tin foil hat stuff this stuff is basic. Some people have put such an enormous amount of personal data out there a hunter force has a huge head start. For those that don't have a clue about any of this a grasp of some of the fundamentals can be gotten from watching the stack of video starting
here.
