> I think copyright (and by extension intellectual property) is not all that important to promote the arts
The obvious counter is: if I spend 5 years writing a brilliant musical, and someone else takes the script and score and produces it worldwide, where is my incentive to make such a brilliant thing? You seem to be promoting a world where people with resources can steal the best and latest free ideas out there and commercialise them. I don't see how that would work.
> One of the ways to do that is to give freely to society.
People can give freely right now. You're talking about forcing people to not be in control of their work.
