i think it as a way that people can go back in time, like ancient times. When people used spears and bow and arrows to hunt. Sort of a way to prove to yourself that you dont need to relay on modern technology to live. A way to connect with your 1000 BC self. Nothing makes me hungrier than watching those documentary survival shows spear a fish in a river and cooking it over an open flame... the same way we did way back then.

But those guys with RVs and stuff are pussys, thats not connecting with your ancient self.
