What is should not be, is a way to remove the sharing of knowledge, which is detrimental to society as a whole.
Fictional works, editorials, opinion pieces - these may be based upon facts but do not explicity provide knowledge that needs to be shared.
Science should always be open, for the sake of humanity. Those who make the discoveries may gain status and reputation, but those discoveries should not be kept for personal/commercial gain.
Art and music, much like celebrity status, are more difficult to judge. Wanting to make everyone aware of who you are or what you have created, whilst simultaneously demanding that they pay for the privilege, seems at odds. You can create for commission, the payment being from the person that made the request, but then they should be free to keep it private or make it public.
We are obsessed in modern times, that we must be paid for everything we do - largely because governments and businesses have made this so.
We barter our skills for things we cannot ourselves produce, but knowledge should never be kept private for an inclusive society - that is the way towards elitism and power, which is clearly where copyright has travelled.
Should you be given food for free ? No. Should the knowledge of how to grow food be free ? Yes.
Barter the tangible, not the intangible. The 'knowledge' economony is a parasite on humanity.
