Occam's Razor doesn't say that the simplest explanation is automatically true; it just says that if we can't know for sure, and we have to choose between two equally valid hypotheses, then we might as well assume the simpler one.
This being a real-world situation, it should be possible to figure out what's really going on, which is what California seems to be doing. No reason to make unwarranted assumptions either way in the mean time.
