My argument is that the grant of monopoly is a regulatory decision and the real cause of "winning". No amount of DRM would confer the same benefit because the ability to bypass it through piracy would be totally legal with no economic or other consequences and so a robust cracking and distribution ecosystem would emerge. Thats a drastically different story than when napster gets shut down, and limewire gets shut down and pirate bay gets shut down every time it relaunches. Imagine a world where there is are 1000 pirate bays

I think this is largely an incorrect take. DRM is anti consumer, not anti piracy. In fact, it has done very little to deter actual piracy (and remember it only takes ONE person to break the DRM), while affecting some casual pirates and all legitimate users. In the process, they got rid of reselling stuff you own.

It's anticonsumer, not antipiracy, never forget that. It means something like this would have happened regardless of pirates.
