This is a nice pseudo-ancap/libertarian talking point but it doesn't bear any resemblance to reality. You're only able to thrive (with or without your neighbors) because of the absolutely massive support structures in place currently. Your efforts and ingenuity have very little impact compared to those, and a bit of luck thrown in for good measure. To see what you get without those support systems you have to look to places like East Africa.
