Even you aren't identifying cause and effect though. Copyright postdates the printing press. Is it copyright or the printing press that led to the explosion in books? Then if you look at technology like the internet, there's plenty of people creating things, not for monetary reward, but because they enjoy it.

As such I would limit copyright to a much shorter period.
