I'd absolutely vote for that, but the interest is just not there - yet. Recycling and water management will be a big thing in the future, but as well controlled by financials.
I do think that a billion tiny communes can have a big effect, as we experienced them for centuries in villages. There is a lot more potential there than people give credit. And it can be very practical to have them within a state, as that won't go away and values won't miraculously re-appear. But on the basic need level, villages are the go-to for me. Much can be done when people have the right mindset.
Digitally, yes, I'd be in for that, too. I am, commenting here. There is absolutely potential in digital communities. The thing is that digital communities do not have the same abilities to quickly help each other on a material level. Sending a meal via Uber eats to a member who's sick is a nice gesture, yet still anonymous compared to stopping by at the doorstep and checking in, exchanging a few words in person. Digitalizing that is a mistake in my opinion, it further fragments society as we look for like-minded people far away instead of confronting ourselves with the dissent we receive when discussing with our neighbors. That confrontation is needed, accepting the other as such, as different, and learn with that.
