I'm not convinced that that's true, and even if it is a huge chunk of population (world, US, pick your area, it applies broadly) keep fighting to regress us to these periods.
People complaining about rules they don't understand is in some sense as old as the existence of rules, but the internet has dramatically increased the number of people who consider themselves experts on politics, healthcare, construction, electrical code, and every other topic on the sun, and who are proud of ignoring the science and the rules and who go out of their way to avoid permits, inspections, etc.
At the same time a significant chunk of the population works to defund and defang all government, preventing the existing rules and codes - labor protections, fire protections, food safety protections, etc. - from being adequately monitored and enforced.
So you have a huge mix of things which are old and degrading, things which were never built right, and things which people are actively modifying in dangerous ways. People have a false sense of confidence build during the years where we were enforcing these rules; I do not believe that confidence is still warranted.
This isn't helped by actual bad rules and regulations on the books. Some minor examples are the prop 95 warnings on every damn thing or the way CAFE standards work to encourage the sale of more pickup trucks. I don't blame some people for wanting to scrap the whole regulatory system after encountering enough of these.
Regulation can used to save lives and improve outcomes, but it can also be used to suppress competitors or favor a particular business practice and stifle innovation.
Would some places have become what they are today had they not built their subway system when it was opportune or hilariously less expensive than it is now? The good things we can iterate on or refactor now would have way more overhead to build from scratch at todays standards, not all of which are inherently useful or justified. Sometimes a whole city burns down or all the labor was forced, which sucks and we don't want, but sometimes you're having to get shadow studies done to build anything higher than a bungalow
As an insurance buyer, in a hypothetically ideal market situation, you would want all those who also purchase from the same insurer to have the lowest risk of needing an expensive claim paid. The lower the expected payout * risk of disaster means lower premiums for the insurer to still make an expected profit.
I think what will happen is simply: Houses are built in places which are more insurable, existing danger-prone houses will exist until they are destroyed, until then they will increasingly be status objects for the elite who can afford the loss and have inaccurate risk appraisal. The fact that so many valuable objects are kept in Malibu/Palisades homes despite fires happening there a lot (as recent as 2018) indicates homeowners in disaster-prone areas aren't acting perfectly rationally.
