They nearly had me with the developer sponsorship joke too. In this video the point is made that not every new development is geared toward living compared to stretching profit as much as possible within regulations. Overall they make the case that:

subsidized/affordable housing > vastly increasing the supply in any way > doing nothing and restricting any development.

They also take issue with modern shoebox apartments in highrises be called luxury housing, when there is more pushback against high density development compared to single family mansions which should be the real luxury development.
