I wonder if there is value in splitting copyright into two parts and keeping a longer duration on the copies of the original work, but shortening the duration on the concepts in that work. That is, allow an author / studio to retain a long duration ownership of the original movie or story, so no one else can just start distributing copies of their VHS tapes after a few years. But at the same time, after 10 or 20 years other people can start making new Star Wars universe movies and books without licensing it from the original artist/author. If the original was good enough, then the rights to be the sole distributor of that original material should be plenty worthwhile, and in the mean time, just in time for the generational “nostalgia bump” a whole new set of related properties can come out, reinvigorating interest in the original.
Maybe even some sort of gradual opening of the IP, where after say 10 years, broad categories are opened (think things like “the Jedi” or “the Empire” or “Endor”), but specific characters and their representations aren’t (so no Darth Vader or Luke Skywalkers), then after 20 years you open the characters themselves but only derivative works. And then finally after 30 years or so you open the originals as well for things like translations or “de-specialized” editions or what have you. Then finally 50 years puts the raw originals in the public domain as well.
