Just ask yourself if Avengers - if the entire franchise of Marvel movies - would have been made if not for IP protections that allowed the costs of making those movies to be recouped; that allowed those movies to be profitable for the investors.
Ask yourself if we would have all the books we currently have from Steven King (or George R.R. Martin, or Stan Lee, or any other commercially popular author) if copyright (a form of IP protection) did not exist.
The answer is "No".
