If the buildings, I assume single family houses, were built in places that few people want to live, or places people are simply forced to live because they can’t live where they want to live, then it wouldn’t shock me if someone chose the bulldozer as the best option. I’d argue that the root cause is bad land use law that doesn’t allow construction in the places people really want to live, but that’s a whole other topic of course :)

My argument, both for AI, railroads, telecom and construction, is that if you built something tangible and useful, it can outlive your financial arrangements, and go on to serve humanity, even if you go belly up.

But for residential construction, location is everything, you could build a theoretically useful building, but in a location that few people want to voluntarily live in, far from jobs services, shops, friends, and family, etc. Ofc, you could build a railroad between two unpopular destinations, or run a fibre optic line between two places with little demand, and those would probably not outlive your finances and might be torn up or abandoned too.
