There are a few people around the world who live in this way as part of the land, but most of us wouldn't know about them as they are not generally part of the society that we live in and therefore don't use computers, book publishers, TV crews etc.
what Avalon said.
I met a couple of folk when i was at a three day rave at Clunie Dam near Skye. They basically lived in the woods all year round, roaming over Knoydart, Lochaber and beyond. they are mental hardcases with outstanding criminal charges and they will never sit at a computer writing about what they do. it is possible but i think in this day and age, one needs extra motivation to persist with an extreme outdoors lifestyle.
There are still plenty of folk living in benders in the woods as well, some i know have done well at it.
