The key here is
incremental development.
So, I'm really into municipal finance and fixing the housing crisis, which got me into Strong Towns. There is a solution, but it's not one that is going to make everyone happy (obviously), it is the state facilitating or even gently subsidizing incremental development.
If everyone is, by right, allowed to build the next larger "unit" of housing (for simplicity's sake, suppose 2x sqft[m2], height, and housing units of the median residential building within a half-mile radius), but not allow to massively build piles of housing on one site, then we effectively solve both problems.
Firstly, this allows for a massive amount of housing construction, with market incentives driving it. Out of the gate, you have the potential to easily double the housing supply. Secondly, the profits from the housing must be more-or-less distributed to the existing homeowners, and the potential to lower property values by building non-like for like housing doesn't exist. Neighborhoods slowly evolve, they don't rapidly change. Third, it incentivizes homeowners to build-to-last with the next stage of growth built in, because it's much cheaper in the long run to build a structure with the capacity to stack another unit on top than it is to tear down a building and rebuild the unit at double the capacity. Finally... and this is the thing that most people miss. It's fast. Smaller-scale developments need a much smaller planning phase, and there are many, many more of them to be constructed. This supports economies of scale, instead of the existing system, with all it's red tape that only allows a few actors to wade through the legal system for large developments. This should create a wide construction industry instead of a narrow one.
I really think the housing crisis is solvable with the top level government insisting that incremental development be allow by right, and that larger scale developments be put up for local review. This allows a city to grow organically, instead of all at once, but only at specific sites.
