Sounds like a Rainbow Gathering.There are still some areas, in South America and Africa, where primitive tribes continue to pursue a hunter-gatherer lifestyle with little difference from Stone Age times.
Perhaps you could go live with them for a few years. If you survive, you can come back and tell us all about how better it was than air-conditioning and modern medicine.
Until you've had some experience of living this way, I consider your views likely to be romanticized, looking at the concept of primitive living through rose-colored glasses as it were.
Have you ever spent a week in a wildnerness area, living off what you can carry in on your back? This is far easier than living a Stone Age lifestyle... and it can be fun for a while, but eventually it becomes a bit wearisome and you're ready to return to civilization.
On several occasions, I have gone with my son and a large group of like-minded folk into an undeveloped area and built a temporary "village" in the middle of nowhere, with what we could haul in our vehicles or build on-site, then lived in it for up to a week.... then tore everything down and made it disappear like it had never existed. For the duration, we lived a little bit like a "tribe" of sorts... we cooked communal dinners and ate together, worked together, socialized together... had people who were in charge of security, of cooking and logistics, of sanitation, of water supply, etc etc. It was fun for a week or so... but after a while there are things about civilization you miss and you're about ready to go home.
Still waiting for you to fill me in on all this wonderful social stuff about primitivism that I'm missing....
