Wait, wouldn’t it make sense for an anarchist to opposite intellectual property law on the grounds that the only way you could possibly enforce it beyond those in one’s immediate community would be with a larger state and associated law enforcement apparatus, which an anarchist would be expected to be against the existence of?

I’m not sure that has much to do with AI, and if anything, AI companies should somewhat like copyright since what they are ultimately selling is a form of software, which is harder to profit off without such law. They just want the concept to apply selectively so as not to impede them.
