Honestly, I think that's what the Bay Area needs to aim at. But of course it's probably more impossible a problem to solve, even more so housing issues.
I think this was one of the points of the article - that this isn't a SF specific problem. The entire region needs to get together to start to plan better for growth. Lack of housing isn't a SF problem, it's a problem for the entire Peninsula. (I'm not as familiar with the Easy Bay).
With decent urban planning, the region could maximize its growth potential. Without it, we'll have major issues in the near future.
