I have lived in the centre of a city in a victorian apartment block and looking back it was a dream. About a foot of brick wall between me and the next flat either side. Never heard a peep, excellent WiFi.
Hard, hard no.
Or, if you are not being sarcastic, the solution to wireless networking issues is to… rebuild cities in which billions of people live and spread those people over… where? Never mind the fact that cities are the best way of arranging lots of people, where would you build those "houses not so close to each other" that is not a desert, a cliff, or an ocean?
“They’ll have congested internet!” would go well alongside “It will block the sun on my daily walk on that part of the street!”
Are they legitimate worries? I don't know.
But certainly more legitimate than congested internet and shade.
