I don't think making semantic distinctions is what the copyright discussion needs.<p>The video says that theft leaves one less thing behind. Copying a song leaves one less sale (or one less potential sale) for the company that owns the song. That copying a song is not a physical act resulting in one less song in one place and one more song in your possession is an irrelevant distinction.<p>Copying may not be theft, but both copying and theft are ways of acquiring something through inappropriate means at someone else's expense.
"If copying isn't theft then I suppose you won't mind if I copy and turn in your term paper before you do (thus making your paper worth less). After all, you still have your term paper right?"<p>I suppose I should take heart that those condone copying/stealing others creations must have some conscience left. Otherwise they wouldn't have to resort to such weak rationalizations as this.
