This isn't a bad idea and I would vote for it, but I can't imagine the political battle to build this would be any less hard than the one to fix density and transit issues with the land already there. Americans don't love to hear this but the political battle here is fundamentally a class war between the people that own property in California and the people that don't. The haves will also fight this proposal for the same reasons they are financially incentivized to fight the proposals to improve the existing land. You can technology your way out of some political problems but probably not this one.
