Your notes are quite wrong. Most regulations are not about not killing people with checks notes state-of-the-art-1970-technology.

This is even more true in zoning. There are much better ways to build homes possible, but not when a regulation is phrased in terms of distance between wooden stuffs, rather than safety and durability.

Economies of scale continue to mean that entrenched technologies get used.

Pilot licensing is especially onerous, where control systems allow flight to be a lot simpler, and a lot of very hard-to-fly technologies (like autogyros) can't be brought to mass scale not due to technology but simply due to regulation.
