But our current copyright model is so robust and fair! They will only have to wait 95y after the author died, which is a completely normal period.
If you want to control your creations, you are completely free to NOT publish it. Nowhere it's stated that to be valuable or beautiful, it has to be shared on the world podium.
We'll have a very restrictive Copyright for non globally transmitted/published works, and one for where the owner of the copyright DID choose to broadcast those works globally. They have a couple years to cash in, and then after I dunno, 5 years, we can all use the work as we see fit. If you use mass media to broadcast creative works but then become mad when the public transforms or remixes your work, you are part of the problem.
Current copyright is just a tool for folks with power to control that power. It's what a boomer would make driving their tractor / SUV while chanting to themselves: I have earned this.
