It's only real if you believe it has value. If you choose to say copyright is made up and doesn't have real value then it isn't real to you, but recognize that it's arbitrary as others will believe in the value of copyright so still has value in their eyes. e.g. Taking a copyright from someone (if that were possible) would cost them like taking a fee costs them--losing something they value.
