We could do that by limiting copyright to just 10-14 years. All platforms could have all that content forever without paying a dime. New stuff and exclusives would still be a draw to attract people to one platform or another.
Today you can instantly distribute media to the entire planet at near zero expense. If you can't make money after a decade you have only yourself or your product to blame. Also, it's not as if once something goes into the public domain all income stops either. With even a small amount of effort creators can continue to successfully package and sell their stuff to the fans even when it's avilable for free. It's worked on me several times in fact.
