I think local decentralized systems of power (energy), food and governance would be the answer. Add crowdfunded community projects and complete open transparency and boom you have a sustainable system of anti-fragile nodes. Farms on Every Lawn type reality. Giving power back to the states is IMO the right direction. Have different states appeal to different people.
But this is all a pipe dream haha, these big systems and corporations that have created our modern life are some kind of necessary evil. We all love not living the agrarian life, but I do believe we live in an age of abundance and awesome technology, we might be able to flip the script.
I don't know my friend, it might not be necessary to revert to the "agrarian life" specially if we develop complete automation... which, in fact we are actively working on.
So I don't know if this is impossible at all...
