how about: tiered copy rights?
after 5 years, you lose some copyright but not all?
it’s a tricky one but impoverished people should still be able to access culture…
Probably allowing everything but producing reproductions.
Basically they could use the ideas from the book and whatnot to do whatever. But they couldn’t just print duplicates with a different cover and sell them for cheaper.
What does that even mean though? Like, you would retain the ability to sell and modify it but not a monopoly on free distribution?
I think 10-15 years, i.e. the original copyright act in the US (14 years) is totally fair, and allow a one-time renewal if you can prove it’s still available for purchase and losing copyright would impact your livelihood or something.
