there's nothing preventing you from slowly moving out into the wilderness Yes, there is - people don't exist in a solitary state; they only can survive in groups. It requires dozens of humans to band together for any chance of survival and reproduction. Even then it can't just be done in a vacant lot; it requires an ecosystem such as only exists today in national parks and reserves, where hunting and gathering is not allowed. So just because a single person can't just walk into the bushes and survive, doesn't mean that the 21st Century urban lifestyle is superior to a hunter-gatherer society in every way. It's not an either-or: both have advantages.
