As someone who also lives in California, can you point out the parts of the state where there's nowhere left to build? It certainly isn't any of the places I've lived (Beverly hills, SF, East Bay), each of which has seen significant commercial redevelopment in my lifetime. None of them are dense by global standards either. SF only has 25% the population density of Paris, for example.
