Overall point: There is a potential solution to the housing crisis for almost every city. It is too early to tell if it will work. But it looks promising. Steps: 1) Build electric cars (exhaust gases in tunnels kill people). (Completed 2020 - Tesla) 2) Build tunnels that are 1/10th to 1/1000th cheaper than current technology. (In Progress - Boring Company) 3) Build tunnels that connect cities and the infrastructure to make city to city commutes through a tunnel but walking on foot using tunnel bus-like vehicles, easy, cheap and safe. (In Progress - Boring Company) 4) Build a test town of 1k-10k condos and connect to a major city with Boring Company tunnels. Initial cost of a test would be $500mil to $5bil. (Not started - ?) 5) Reduce the cost of building towns through 10X or better infrastructure improvements and develop a franchisable business model around towns. 6) Franchise the towns. Result: Housing supply goes way up near where people want it right now. NIMBYs can't stop it. Investors may lose their shirts or make massive profits. Advantages over other solutions: This only works if the business model works out. It leaves the politics of land-use within cities almost completely out of the picture. Disadvantages: Its never been done before. It will cost a LOT of money to test it. The investors must be in it for the longish haul: 5-10 years at least.
