Deconstructed
Since you have already lived in the modern world, I suggest you get out in the wilderness and survive without any modern assistence.
Your post has its fair share of misguidedness, but this particular suggestion's problems should be very obvious. Obviously your hypothetical Traitorfish (based on reasonable but unconfirmed assumptions) has not spent his life in the wilderness and is not adapted to it, and would not be able to draw on social support networks there; equally, a Papuan highland hunter-gatherer has no more experience in this world. His struggles coping with this world would represent nothing more than the foreigness of his upbringing to another way of life ... so it is with your hypothetical construction of Traitorfish. Completely pointless line of argument.
