Our instinct is to regulate and tax the technologies that are being pioneered in California, in the misguided belief that it will give us some kind of competitive advantage.
I don’t think that that’s the reason for regulation: it seems to me that US companies traditionally don’t care about externalities (environment, privacy, accessibility, etc.), and regulation is required to bring them into line. That doesn’t always mean that their business model will survive unscathed, but that’s generally a good thing.
