yes you can live without money but it is nice to have money. Stupid question for english Do you know how to make your own clothing from skinns or even plant materals? I can make a shirt from skinns but you need to whats the word?..I dont know you have to mess with them. get off the skinn and such.
ok lets say you can make clothing for when yours rips out in the woods. You need salt. you can get salt from animals but it sucks not having salt. I went camping for a few weeks once and all i could say about the food is that it would be better with a little salt.
now with a little money you could emerge from the woods every once in a while get a few neccisaties that you cant find or make. Also it is very easy to use up all the food in one area of the wilderness. Forests are balanceing on a pin adding a large predator into the food chain might upset it and youll run out of food. this is why large predators are spread so thinn.
you could farm and fix this problem but do you want to go out and find seeds? you could its possibul but it would suck. You only need to buy seeds once if you are not a dumbass and you save a little of the crop.
so what im saying is that you could live out in the wilderness without money but it would be hard and the idea is to enjoy your self not to be constantly starved, alone, if you miss so many hunts like say if you get sick then you starve to death. Yep nice to be self sufficent but if you kill all the pray eat all the plants and you have no farm its nice to walk into a McDonads, filthy, whearing home made clothing out of rabbit skins, and talking to your self.
