I would like to see the end of subsidized homeowners insurance, such as the National Flood Insurance Program. Most, if not all mortgage lenders in the USA require a homeowners insurance policy. I'm happy for people to build wherever they like, as long as they are assuming (by paying to build it themselves) or transferring (by buying insurance) the risk.

When insurance is subsidized and you transfer the risk without paying full price, it distorts the risk calculation and leads to homes being built in places that maybe they shouldn't be.
