A HCOL city brings a bunch of things together that you can't get all together elsewhere. Critically: 1. Jobs 2. People 3.

Or you can live in a small town with far fewer job opportunities, far fewer people, and far…
That explains the draw of SF vs Monterey, but not necessarily SF vs Houston. Why do the most prestigious cities reliably stay the most prestigious cities, if not for the prestige itself being the draw? As I said, I'm grasping a bit because I'm not sure I fully grok it. But there is something that would be lost about Manhattan if it became cheap. I believe it's not just the three items you list, but also the concentra…
I will concede that for some portion of people, the prestige of living in San Francisco is a part of the draw. There are other factors that are probably more important for a lot of people, though. Comparing to Houston, San Francisco is literally 5 times as densely populated, which changes the feel of the city drastically. Houston is larger in terms of population, but it's also massively sprawled. That sprawl drives down the price of homes but also makes much of the city feel like the suburbs (probably; I have not visited).
Houston also spends >100 days/year at >90F, which makes it not comparable to a coastal city for people who do highly value temperate weather.
