Can't say that i agree with all of the points in your post but A for effort. Then again I live in Ireland we bought a nice country house and could raise a couple of sheep here. Hopefully will pick up some land after a good crypto bull run and have options.

Poorly insulated, no passive solar heating, and the most important thing, no yard. No place to grow all the vegetables you need to eat each year. No place to grow farm animals for meat that you need to eat each year.

I do think that this will become more and more important as food is mass produced and the population keeps increasing. Self sustainability is the way forward.
