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.

Yes - agree. I am being provocative as well (HN doesn't like, but sometimes it's useful).

This is a problem of policy and social engineering - technology can and will help, but it won't solve it.

Lol, imagine thinking that the undersupply of housing in US metro is due to the market having too much say.

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.

There are better ways of expressing this valid notion.
