Sorry to be a buzzkill here but...

The reason why people moved away from crafting their own things was because of something called "comparative advantage". It's a basic economic principal that says that a group of people can produce more overall if each person specializes in what they are good at.

If you were born an had nothing and didn't trade, do you honestly think you would have figured out how to build a computer and put it in your "residency" (that you built yourself) and get on the internet right now?
