I don't think making semantic distinctions is what the copyright discussion needs. 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. Copying may not be theft, but both copying and theft are ways of acquiring something through inappropriate means at someone else's expense.
