Man that is an absurdly difficult issue to address. Yes, you are right that copyright is just awful for everyone. But really the problem is not copyright per se, it's that (for example) Amazon preferred to burn hundreds of millions of dollars to get the rights to an IP when they were going to make up their own story anyway. If Tolkein's work were PD (which it should be, btw) it would have saved Amazon some money but they still utterly lack any good ideas and felt that being linked to a famous work would turn a terrible set of scripts into a sure fire winner.
