Sounds to me like you're describing farmer's markets or farmer's co-ops. If your government is failing to provide these services the only alternative is to buy land and do it yourself, but you may even get pushback to that too depending on how you want to structure the co-op. As far as I understand though in the USA there's not really legal barriers to structuring a co-op.
In Taiwan we do have lots of these kinds of things you describe, especially outside of Taipei. Seems every time I motorcycle through a smaller village I always see a farmer's co-op. I'm not sure if the government set them up or not, but I'm pretty sure the government built the ubiquitous enormous covered basketball court that I see in every tribal township that functions as a playground, market, and wedding venue.
