You're absolutely right - that
is the main issue. I'm not suggesting for a moment that fixing labor union litigation would fix housing. It wouldn't.
I was using the pipes as an accessible example of what is a single piece of a very, very large mosaic.
The assertion I intended to make was precisely this: That it is impossible to point to a single bad actor (although, you are likely correct in pointing out the most egregious of them). The core issue (IMO, the thing to fix) is that the system of incentives that surrounds the developers, contractors, politicians, homeowners, and everyone else involved rewards slicing the pie over making more pie. Adding value, when it's easier to litigate your way into aquiring a larger share of existing value, is pointless from any individual's standpoint.
Take a look at the debacle that surrounded the Stuyvesant Town housing projects - this is a case where this sort of pie-slicing quite nearly made it through, but was struck down by the courts. I use this example because due to it's failure the techniques involved are clearly visible:

...my central assertion is that the pipes and deals like this are motivated by the same underlying socioeconomic factors. And too many lawyers.
