For something like 20,000 years we were all shared owners of our legends and stories, and recently that's changed. It doesn't make sense to me that the kids that grew up on pokemon are prevented by law from making their own stories, art, and games about this shared cultural history.

This idea that the corporation that spawned the thing "owns" the idea is absurd. The creation is borne of the input of our culture, the output belongs to the culture. If you wanna do a capitalism in there 20 years should be more than enough time to do so. 70 years or whatever the USA is at now is absurd, madness.

Public domain "IP" had lead to phenomenal art that's been capitalistically profitable. Sherlock Holmes, multiple profitable movies, tv shows, and videogames. Greek mythology, multiple award winning videogames and movies, same for Norse mythology.
