That's true in that case, but strictly it isn't quite true that any act that doesn't involve copying isn't restricted by copyright law.

E.g. in the EU, doing a public performance of a work is restricted by copyright, as is renting/lending to the public, though neither involves copying. (Don't ask me why someone thought it was a good idea to make copyright cover renting/lending, but there we are: http://goo.gl/WneMs ).
