A lot of the things we do on a daily or weekly basis have ways of doing them that can either be private or communal, some of these which we do not think to consider as having that characteristic.
For example, bathing in the Roman Empire used to be communal, but then Rome fell and citizens in the splinter countries began taking baths privately.
Receiving mail is another example. There are countries which don’t have mailboxes and everyone gets their mail at the post office in the PO boxes. It was the United States which pioneered the idea of the modern mail system, which is why we associate it as a private act.
There are activities as well which don’t have any history as jumping between one or the other that might benefit from it, for example I think towns might benefit if internet was free and freely accessible but only at the local library.
What’s a non-communal aspect of life you think should be communal?
I sometimes think about automats, and what a modernized version, designed to both be healthy enough to eat as one’s primary meal source without ill effect and efficient enough to compete in price with home cooking, might be like. I suspect it would probably involve a lot of soup and chili and the like, just because that stuff is relatively simple to produce in large quantities, and uses cheap yet generally healthy ingredients
