I'll add, I don't think we should be developing new housing on any of our wild lands. Not our beaches, not our mountain passes, not our forests or wetlands or grasslands, and certainly not Muir Woods. What I'm calling for is to allow the owners of existing single-family houses in urban and suburban job- and transit-centric neighborhoods to voluntarily tear them down and, if they choose, replace them with multifamily housing of, say, four stories.
