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?
In such a system, people would still have their own devices that can connect wirelessly to a library, even from outside the building (people who live immediately near the library I work at get free wireless internet, at least from 10 to 8), it’s only the signal that would come mainly from the library.
Another factor that comes to mind that I forgot to mention in my other replies is that the internet comes from undersea cables that are long enough to wrap around the Earth 180 times, which then enters into servers which then enters into cable lines which then reaches peoples’ houses, and these are all an absolute hassle to maintain, both because of wildlife attacking them (yeah, a single fish can take out a country’s internet) as well as bad actors, and on the cable side, bad weather can take them out. The service strain would be a lot less if we didn’t try to put too much on our plates, allowing more maintenance to be maintained.
