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?
Rural Japan here. It would take me more than an hour each way to get to the post office (75-80mins). Ain’t no way when I generally get time-sensitive documents at least a few weeks each year. Also, especially rural but even suburban and urban Japan is generally elderly and has less mobility.
We do have to go to a post box to drop our outgoing mail, though, and I think that’s much easier (that’s a 10-15 minute walk) especially since that’s generally a rarer action.
So why not have an ingoing box next to the outgoing box? My initial comment was for packages but it works for mail too.
