This sort of construction failure is present everywhere where the public is allowed to make extensive inputs into what gets built. It is not just a US-specific reaction to urban engineering by Robert Moses.

We've let the pendulum swing too hard and instead of a dictatorship of technocrats, we have a dictatorship of vetocrats. A relatively small group of people, sometimes one single individual, can make new construction more complicated than lunar exploration, and there are indeed neighbourhoods whose permitting process took longer than the entire Apollo project.

I live in a house built on a former brownfield, 32 semi-detached houses in total. The whole project was delayed by four years by one dedicated octogenarian who didn't like the idea of new people in "his" neighbourhood and pulled out all stops he could (or even couldn't).

What do you consider to be anglo incompetence in dwelling construction that isn't NIMBYism?

You can tell the difference by observing that, intra-city (not inter-city, inter-state, or inter-country, which introduces confounds), the suburban locations with the highest land values build the least. Enclaves like where Marc Andreessen lives, where his family unit has been involved in successful NIMBY activism. That is an outcome that can only be explained by asymmetric government interference due to more effective lobbying from politically active NIMBYs.
