Lol. We can sustain and oversupply right now BECAUSE people do their jobs. This becomes absolutely impossible if people just stopped. Do you even have the slightest idea how many people have to do their job in order to build the simplest of machinery needed for modern farming?

Who is building the machines and equipment needed for that? Ok, just for fun - let's imagine someone still does that in your world without jobs, why would they just give it to you or someone else? In exchange for some bones and pretty stones you've found in your backyard? What can you possibly provide that's worth even a fucking tractor? This is so delusional I have really no words for it.

If you think it's so easy and great then go get your like-minded buddies and just do it. What's stopping you? Nobody will care if you play somewhere out in the wilderness.
