Somewhere between anarcho-communism and anarcho-syndicalism, with a strong dose of social ecology. Small communities—however sparsely (rural) or closely (urban) packed—governed horizontally through consensus models, and federating with one another for larger projects and to form responsive and resilient decentralized networks of distribution. (I'm not limiting "community" here to the strictly geographical interpretation of a communal neighborhood, though that's certainly one form; others would be worker-owned-and-self-managed cooperative enterprises, recreational clubs of various kinds, etc.)
Find ways to build successful but non-growth/non-profit-centered industries with modern technology but without the expectations of rampant consumerism, and with governance models strongly influenced by more horizontal and matrilineal societies, past and present. If we can't do it and keep smart phones, then sorry: ditch the smart phones. If we can't do it and keep modern medicine, then prioritize refining the model so we can.
