It sure seems like you're trying to force a perspective without taking some fundamental human nature factors into account. Or deliberately ignoring them. But

It sure seems like you're trying to force a perspective without taking some fundamental human nature factors into account. Or deliberately ignoring them. But I'll go with just not realizing one thing... there's a lot of things about close quarters residency that a great many people ACTIVELY F'ING DESPISE. Noise, smells, and just... well, meet enough people and you may develop slightly less positive opinions of them as a whole and choose to live with some degree of space/separation that's not "ideal" from an efficiency standpoint. Sure, the numbers say living like a meat popsicle is absolutely more 'cost effective' but that's a hard-pass from me.
