Did you not say in your opener:
> It is bad for a state
I should have appended the other statement with /s
That is to say, people don't typically move to California because they love the legal system, it's typically for other reasons like our weather, economy (jobs), diversity, schools (difficult to find hard data, but just search for it and see what things you see listed). Even in the case where someone does base their moving decision on a state's stance on entrepreneurial mobility, California being many years ahead of this FTC decision would only make it a better candidate, not worse.
Others passing the same measures years later does not make California seem "bad" in comparison. It would signal that they're just ahead of the curve on the issue, so I think your take is flawed.
