Copies do not exist.

Copyrights are very interesting stuff, until one realizes that for many copyrighted items, there is no perfect copy. Every version based on a previous one is different physically and from an information point of view. So there is no such thing as copying, just producing a seemingly-similar object based on the first, original object.

Of course, there are things which can be copied identically, like program code on a computer. Those things can be copyrighted pretty fine.
