This argument requires me to believe that Warner Bros would see no difference in value between a property that becomes public the moment the author dies and a property that has 70 years of exclusivity after that point. Obviously, the difference in value between those two properties is immense, and that value is realized during the author's lifetime.
Only the first few years after publication matter, because that's when virtually all of lifetime revenue is earned. Revenue earned beyond that is usually not enough to even justify proper preservation, leaving huge archives to rot away.

I can make you a list. Cinderella, Sherlock Holmes, James Bond, Superman, Batman, Lord of the Rings, Star Wars, Harry Potter, Marvel, Game of Thrones... You could sell WB the 2090 rights to any one of these, except the ones that are going into the public domain (and those they already own of course). Look at that, the system is 'working'.
Good luck selling a movie to Warner Bros on the premise that it'll be a real money-maker in 2090s on telekinesis-vision platform.
