Maybe in your country. Here in France AirBnB are both cheaper and the rooms are nicer than hotel. Some of them could be landlords and profit… but some others rent something that would not be fitting as a location (like a vacation flat or a subpart of a house) but is OK for staying just a couple of days.

So I disagree heavily with your generalisation

I disagree that you owe a face to face conversation. No one should forced to go meet someone if they don’t feel like it.

In the context of dating, if you get ghosted, consider that the person is not interested in you after all - and just move on. No big deal.

People will volunteer to do the job because it is something they (and everyone) needs done

I did volunteer work in several associations. From personal experience I can tell you that “someone will do it, a volunteer will rise” should not be relied upon. I have seen many instances of tasks that everyone was aware of, and yet no one wanted to do; even though they were important. At the end of the day, guess who completed them? The president of the association, because that’s their responsibility ultimately; until they got sick of always doing these tasks so they did not want to be president again the next year.

In the case of a society where no one is responsible for given tasks, I can only guess that vital tasks would be left undone and the whole society would be collapsing. Imagine getting your electricity cut each day of “insert your most favorite celebration here” because no one felt like working during celebration day. Imagine fire becoming widespread and burning every building because at that particular day, there were not enough people with fireman skills around to extinguish the initial fire

We need to have assigned roles and responsibilities based on our skills. How do we do that in a world where you can say “Na, I know I’m the only expert on this available right now, but I don’t feel like doing it today” and get away with it?

There is a gap between conceiving a system and maintaining it. Sure, there are architects who conceived sewers. But I doubt they went inside to maintain it on a regular basis.
