The cost (no profit) of 1 Million homes where people want to live (where your community is), would be roughly 0.5 Trillion to 1 Trillion USD [1]. So, I don't think this is true :(.
We simply don't have the construction workers and the supply-chains to make it happen. Again, these are fixable problems and I want this to be true. But it is not today.
