I adore this notion sometimes brought up by capitalist bootlickers "if you dont like capitalism just go and live in the woods on your own lmao". While in reality what makes this impossible isn't your inability to survive off the grid, rather, the omnipresence of "the grid". Yep, "living in the woods" is pretty much illegal in most places. How could capitalists allow that? You're a slave, remember. The only thing that differentiates you from a slave is that if you work hard and you're lucky you get to choose a nicer owner.
Living on my own and not getting in trouble with the law would require a tent and some means of transportation, so as to move around quickly and never stay for long at one place.
But then new problems arise:
Heated tents are next to impossible to build yourself, they aren't cheap, they need actual refined fuels, not just wood. Tents in general don't protect you from wild animals.
Since you can't grow anything, what the hell are you going to eat? Some forms of hunting and fishing are allowed where I live, but then again, you need fruits, vegetables, wheat, etc. And even hunting and fishing are only allowed in some designated places.
Ah yes, moving around. Well depending on where you live a bicycle probably could suffice, but in most places not really. You need a motor-powered vehicle. Well, building a biomass gasifier is doable although dangerous. But than what? You gonna build an internal combustion engine too?
None of these problems would arise if you could just get a place where you could stay safe from law enforcement.
