The main factor that I feel that people forget is that once you build something, fixing it requires undoing it and that’s extremely expensive. Like if you design an API wrong, release it, then realize to change it requires a massive deprecation effort (if you don’t want total disruption).
You’ll notice throughout history that things like earthquakes, fires (see Chicago) or wars (see parts of Europe) have had extremely major effects on redevelopment.
Of course, we don’t want disasters because they cause total disruption, but when we talk about redeveloping an area, you can’t compare two entirety different places and just say “oh we can do it because we have more money” — you always need way more money to redevelop than to develop the first time.
