This seems rather unlikely to stand up to court scrutiny, I'd have thought. And realistically, ultimately this sort of protectionism almost never lasts. I'm sure Ron DeSantis, had he been around early last century, would've banned cars to appease the horse lobby, too (and protectionist bans on cars were absolutely a thing in the early days), but there's no future to it.

In any case, this appears to only cover cultured meat, which is not commercially available in significant quantity anywhere, and likely won't be for some time. It doesn't cover quorn and the like (the koji mold product is very much in the quorn category, not the cultured meat category).
