There is one thing they all have in common: they all allow housing supply to meet demand. Anything else is a distraction.
That's like "fixating" on the money supply. Sure, having more of it lowers prices. The point is: how do you get there? What are the side-effects of your proposal? These are not simple questions.
Fixating on zoning, at the exclusion of all other considerations, is a facile answer.
Japan is proof that zoning doesn't have to represent a restriction on housing supply. But don't just dismiss Tokyo because you think other cultural factors are at play: Montreal, Chicago, Dallas, Calgary, and plentiful other US/Canadian cities have confirmed what Tokyo has already taught us.
Chicago city average really hides the fact that the places most people would consider living in Chicago aren't super cheap; still cheap-ish when compared to other coastal cities
All of these factors (and more) result in the housing economy you see in Japan. HN people love to fixate on zoning, but it's not even close to the whole story. If we suddenly asked westerners to live the way Japanese people do, there would be open revolt and riots in the streets.
