Interesting... Perhaps I can offer a way to either experience almost
exactly what you have described, or at least a way to learn more about
the ups and downs and functionality of just such a place.
Almost all Native villages in Alaska fit your description. Some are
a little more one way and a little less another, and others are the
opposite. For example there are very few if any where a majority
of the families own a truck. There are few industries, and the ones
that exist are as you stated: "cottage industry, art, export of
products made within the community...", and money is in short
supply. "Socially-responsible investors" is a good description
of the non-profit village corporations that exist in almost every
village in Alaska.
My personal experience is that Alaskan villages are a very healthy
place to live. It is a wonderful environment for small children.
It is also a very difficult place for teenagers, and a difficult
place to provide adequate high school facilities for.
