1. People still do software based on the GNU license. What's the difference?
2. I'm a mathematician - math is not copyrighted, yet it's still being done.
3. Is it really so important for society that copyrighted movies be based on old stories? Won't society benefit from new stories and characters?
To be clear, I don't propose to really implement it. But the existing system also sucks. I'm thinking that maybe incorporating such an idea into the existing system - limiting what you can do with public domain work - can be beneficial.
