I mean, if you want the counter example; we already have it. Texas and Massachusetts both had much more developed and supported engineering industries + talent pools in the first half+ of the 1900s. Talent specifically moved to California to be able to innovate without the encumbrances of current legislation in those states. Sure, it's more complex than that and there are other reasons. But ultimately, a single piece of legislation had a huge hand in turning California into the preeminent global leader in the vast span of technology industries.
