If there is no IP then why would you bother creating or inventing?
On the other hand, Disney extended the timeline of copyrights beyond reason.
Edit: I understand not everyone needs monetary rewards to create something, however I think there are a lot of things that without the monetary reward would not exist.
Do you like video games? Everyone here seems to think we can just copy the files without any harm to anyone. But if all games were free, what sort of games would be created? If game companies stood to make no money, why would they bother with such a large production? Why would Nintendo bother being Nintendo?
It's not that video games wouldn't exist without the IP, it's that without the monetary reward there wouldn't be such a drive over such an extended period of time. But maybe we only need indie games and no one here has ever enjoyed AAA games. That's fair, if true.
