There's that, but also it's more difficult to get mixed-density builds than detached homes developed, or the type of builds the left associate with "affordable housing".

While being able to build detached homes faster is nice and all for those on the market, for an effective YIMBY approach allowing density is preferable.

Plus, trying to sprawl out into perpetuity is putting cities in the hole. The suburbs are money pits that are subsidized by the city cores.
