With 77 Billion they could have:

-Built better transit to North Bay.

-Built/Complete Bart circuit around the Bay Area.

-Built HSR to reach exurbs of Gilroy (S), Tracy (E), and Napa (N).

That would have given breathability to the bay area.

The barriers to these things isn't funding, it's that certain stakeholders don't want them. The North Bay in particular (taken as a collective entity) is huge on convincing themselves that they're entitled to the benefits of cooperative society but don't have any responsibilities to one in turn.

My pet project (not that I have any influence to make it a reality) is to completely fill up the bay starting from Alviso with concrete and creating housing there. No NIMBY can stop it, we can also flatten the mountains near fremont and use it to fill up the bay.

You are too optimistic. Seattle's ST3 would cost 54 Billion to build 62 miles light rail. And I think such project in Bay Area would be more expensive. So, just pick one
