Rediscovering living in a village

I have seen a movement toward more "resilient" communities that ends up with urban people trying to learn how to emulate a village. Well, they actually end up trying to setup a commune, but eh.

Its not that bad of an idea, have stuff that you can fix/produce locally.

The problem is, humans ran into a scaling problem with that plan. A village can not have a space program. Most villages would never have developed aircraft like that ones that we depend on. Etc, etc.

Designing a lower cost/easier to manufacture {insert farm tool here} can be done without the need to move out to a farm and prove that you can survive without outside inputs (or too many of them).

Making a better functioning community is a good idea, but we can not forget the advances afforded to humanity from trade.
