I appreciate your enumeration of some of the things that have to happen to make a city grow, but I don’t understand how you bring it to conclude that any of these would be insurmountable or unprecedented. Every major metropolitan area in the history of the world went through a process like this. Sometimes within a single generation. If demand tapers off at some point, growth will stop too. That doesn’t seem like an argument against letting it happen. As for “if raldi were right, then why isn’t the whole world Tokyo?”, the answer is that there are precious few places that people really want to live in (barring a state-created housing shortage making it unaffordable). Tokyo is one; California is another.
