What you have proposed is worse than what we have in every way. Transporting food and basic foods over long distances is cheap and very energy efficient. In fact it's more efficient than having a bunch of tiny factories in every city. People shouldn't be stuck living their whole lives in one place working for one company making shitty cloth or whatever.
