I'm very much not proposing building single-family units. See the discussion about density starting at "Wait, how many people are you saying would live there?"
Alright! We can't build multi-story, multi-use, walkable neighborhoods in San Jose now.
Is the proposition then to create more land to work around these restrictions? Why wouldn't the same forces apply on the new land?
What I am saying is that there's enough land already for the vision you have for the infilled areas. Your post is implicitly saying that it's easier to literally create land than change zoning laws.
And it might be, but let's be clear on what the problem actually is -- and the lack of land it is not.
EDIT: just to emphasize: Brooklyn has 2.5x population on (1/2.5)x area, and is growing -- all within the confines of an island.
