Housing co-ops are somewhat in line with what you’re describing but cost more. The home is owned by a not-for-profit entity controlled by its residents. The ones in my area charge around $100 or more per month for food and $200-400 for the room (and most people buy food on top of that), but that’s still cheaper than most people spend and you don’t have to buy extra food. The challenge is that you need money in the first place to purchase the home.

I think the reason co-ops don’t aggressively reduce costs like you describe despite being frugal is that having more varied food and clothing, entertainment, and electronics are worth it for most people. I think people would have to give up quite a bit of personal space as well, which I don’t think appeals to many people.
