Many traditional villages are indeed largely self-sufficient for their food, and also for maintenance of their tools.
For production of their tools, much less so (depending on the tool : pottery and some woodworking, yes; metallurgy, usually no).
And that's not a minor thing !
Minimizing the importance of large-scale support system is a way to promote a (usually reactionary) misunderstanding of actual economy.
