Housing, desperately needs permission-less innovation (completely regulation/zoning free). Maybe not everywhere. But, come on, CA has 163,707 square miles, can we just carve out a couple of those, even if it's just 100 or 200 or so (with enough economies of scale to attract serious VC money), in an area that has no NIMBYs, for build whatever you want and let builders and innovators innovate. We can take what's working and slowly apply it other areas.
At the current rate, the way things are, we're never going to see any progress in housing.
