I don't know. That's a bit like saying that big software projects will rarely if ever be developed as open source. And yet there are open-source operating systems, browsers, databases and webservers that can be freely copied without payment.

I think it's safe to say that without "intellectual property" laws, big-budget films will be funded, produced and distributed very differently from how they are today. That's not necessarily a bad thing.

Anyway, I hope that you are right and I am wrong, because I'd rather have a hundred $700,000 films to choose from, than to have one $70,000,000 blockbuster to watch.
