That's an argument for limited copyright terms. Society grants you free use of all the pre-existing stuff, in return for adding your contribution to the free pool after a certain time. You get a short time for exclusive distribution as an incentive. If you want perpetual copyright, you can't have used anything provided by society, starting with things like language and music notation. Yeah, Disney, society lets you use those fairy tales, and the motion picture camera, and lots of other stuff. Now give something back.
