While I agree that some copyright law probably goes too far, I don't understand how you could advocate for 0 copyright? What incentive will people have to produce creative works in that case?
The main beneficiaries are and always have been large companies with big portfolios of works, not actual people doing the work. And there are lots of business models for big companies that don’t require government making up and enforcing rights and still make profits. I don’t think we should to further and drop patents too which are exclusively used to limit competition and do nothing for innovation.
