You can rewild. There are people out there doing it. I plan on doing it as soon as I get a few things squared away in 'civilized' life.
The biggest barrier to reclaiming your feral heritage is to gain as much native knowledge as you can. Despite appearances, we are all natives, all of our ancestors lived in the rhythm of nature, so it's in your genes quite literally.
But that means unless you've already put some work in to learning this stuff you have a lot of catching up to do. Unfortunately we aren't blessed with the elders we would have grown up with in the old ways, so instead books will have to fill the void for most of us.
For learning how to live with nature instead of trying to conquer it....
Advanced Bird Language by Jon Young
Seeing Through Native Eyes by Jon Young
Anything at all by Tom Brown
Journey to the Ancestral Self by Tamarack Song
All of these will help to fill in the gap for your awareness and instinct. Most people don't understand that everything in nature is ordered, everything is affecting everything else, and you can learn to interpret and get inside this system.
The most important part of thriving in the wilderness is to practice your awareness and tracking. These cause you to use your brain in such a way that most people in civilized society will never experience. It really, literally reactivates your instincts and intuition. This is not a bunch of metaphysical voo-doo, this is the real deal. It will completely and utterly shift the way you perceive the world.
Other important readings...
All books by Carlos Castaneda
Any books on tracking
Any field guides
Any books by Thomas Elpel, the most important of which is Botany in a Day which teaches order in the seemingly chaotic and overwhelming world of plant species and their edible and medicinal uses. *when you've studied this book for a while you should be able to go just about anywhere in the world and make educated inferences about the plant species there simply based on patterns you'll learn to recognize*
Look for elders everywhere and anywhere. The original earth people's probably learned most of their tricks from animals and through their own experiences.
The earth, in the sense of everything not made by people, is your home and it's calling for you always.
Besides, have you ever known that kind of freedom, to be able to wander wherever you wish to go, laying your head down one night under the stars by a brook, the next in a meadow, the next on a hilltop, and the next wherever you choose, knowing the land is going to provide and care for you. It is real liberty.
Plus you'll find your brain working faster and faster, arriving at solutions before you were even consciously considering a problem, memory will improve (actually a photographic memory is a by-product of tracking and awareness skills)
And then down the road, you'll look back and be amazed that you ever floated through life and unconsciously and ignorantly as you did. This may also create a rift between you and people who don't think like you, you'll forget what it was like to wear the blinders and live with tunnel vision, and then you'll have to adjust to being surrounded by those kind of people, unless you stay primitive.
I happen to believe we should have quit at hunting and gathering but maybe we needed to come to this point to realize that we weren't mature enough to use our technology responsibly. I mean think of it this way, the food used to raise itself to the highest quality possible by it's very nature, all we had to do was hunt it and manage the forest if we so chose. What kind of hare brained scheme was it to settle down and start busting our asses doing menial labor all day every day for the rest of our lives? That's no life at all to me! I want to wander and claim my birthright. And so does everyone else, they just don't know it, but each and every one of their cells is screaming for it. It is the root of dissatisfaction in our modern society, the unfulfilled age old genetic cry for expression. Heed the call and see what awaits you!
