There are many places in California where it's easy to build housing.<p>However, those places are not close to where the "more" or "less expensive" housing demand is.<p>To be a bit more precises, those places are at least an hour from the demand.<p>Building in those places won't solve that problem.<p>In addition to not understanding the constraints, the rant about "other countries can do big projects" suggest that the author thinks that the benefits of a solution are somehow an argument for its feasibility.<p>It doesn't matter whether other countries can do something. The relevant question (for US/CA projects) is whether the US/CA can.<p>It's fun to propose things, however, the actual value comes from doing, and the author is completely uninterested in fixing why the US/CA can't do big projects. (Hint: the Republicans/conservatives didn't screw up the Big Dig or CA's high speed rail project.)
