Corporations don't need to be able to own copyrights or trademarks indefinitely in order to profit from producing products, as long as no one else is allowed to sell (or give away) the majority of complete pieces of work that they actually produced.

Notice that plenty of money has been made by corporate media making films about history or pre-copyright literature. Also notice that much of the media produced by megacorps that is capitalizing on their monopoly of "intellectual property" turns out to be really bad, usually because the corp only cares about cashing in to the max, sees it has a monopoly on something popular, and decides to minimize the production quality precisely because its overriding purpose is to maximize profit.
