There is so many of us that want the same thing, it is to bad it is not feasible. We all have influences that makes it so. Jobs, family, schools (kids), and so on.
It would be nice to think about it. Buying land as a co-operative unit. At lest 10 acres, or 2 acres per family min. Each has their own home, pool a X% of the land for garden and pasture for a couple of cows goats, and what ever. A nice Jersey, Guernsey, or Brown Swiss for cheese and butter, a couple of Dexter cows for meat and milk, the same with goats. The thing is work as a group, and when someone goes on vacation or visits family there is always people to care for our chickens.
A large garden with verity enough that we would not be eating a few different vegetables. If you want verity you give up quantity to can. With a large garden there would be enough to can. There was a time when community's would get to gather and can at a community center. We could do our own canning and possessing.
It would take communication and some structure. We have lost that in our. DNA of the 21st Century. But there are groups that are doing just that. To the point of setting up their own home schools for their kids. It is hard to picture a group of all ages, and all stages of life doing that.

It is a thought........ Or a wish.
