What about traffic? The more prosperous Bay Area becomes, more traffic woes, more homelessness, more demand for affordable homes and otoh, no infrastructure improvements, no new public transport system, no new schools, congestion everywhere and higher cost of living.

Everything declines with high density. Medium density is better than low density. Networked public transport systems is better with medium density. More housing stock is good to reduce sprawl but the answer isn’t always high density housing and not subsidized housing. Example: senior affordable housing is good..shared housing is good..affordable micro homes is good for single working people. But affordable housing that crams a lot of working adults and children that go to public schools is not really good. Etc.
