I have seen the 'without AC Texas is not habitable' (or a weaker version 'large cities cannot exist in Texas without AC') sentiment, which is somehow related to what you are talking about, many times on this website. It absolutely boggles my mind. The climate of some of the most densely populated places in Asia are similar to Texas. Those places are densely populated before AC became a thing, and even now there are plenty of people who cannot afford AC.
