From a technological standpoint housing supply is a solved problem. Three story multi-tenant buildings with underground parking and public transportation work great, if that's not enough just build higher.
That would be an economic or market structure, and may be a possible solution. I'm looking at LVT and land use regulation myself.
My initial quip was to point out that (as I suspect @anonymoushn was alluding) the problem isn't technological. Rather it's one of incentives, politics, and market structure.
Lol, imagine thinking housing serving as a speculative asset for global Capital doesn’t constrain and distort supply away from what is needed vs what provides the greatest returns for this class of investors.
