For me, it would be better to focus on drastically reducing the duration of copyrights. At the speed things are going, 2 to 4 years would be good. It would be beneficial for everyone. Drugs, Manuals, Seeds, Arts...
It takes over a decade for most major pharmaceuticals to go through all required research and clinical trials before they ever reach the general population.
Costs can easily go past tens of millions of dollars. A 2-4 year copyright period would require new medications to either be prohibitively expensive, or not be researched at all and only the most profitable diseases would ever get looked into.
It's alright, copyright doesn't govern pharmaceuticals anyway. That's what patents are for and they expire much more quickly than copyrights do though it's longer than four years.
Functional ideas or features are explicitly excluded from copyright or trademark protection.
Just bringing our duration in line with the rest of the world would be a massive improvement. Star wars and anything from that era should be public domain by now.
