People and communities are not that different from each other, so I don't think the idea that each community would benefit from a customized local solution would work. You'd lose the benefit of economies of scale and add a lot of friction to economic activity for no good reason. The workers are also consumers, and would have to pay a lot more for everything because a huge amount of work would have to be duplicated everywhere in the economy, making things more expensive. Large scale is good, the problem is who owns the large scale solution. When it's owned privately, it's easy to abuse such a position of power and workers and consumers don't get the full benefits of scale. The solutions should be collectively owned and managed.
