This analogy really doesn't work at all. The factory does lose money on factory time and employee wages. The music company doesn't lose that time when a song is pirated. This is the same old argument of copying vs. theft.

What this guy (the OP) is doing is showing the straight economics of the situation, morals removed. It's a realistic viewpoint because for most people, morals go out the window when they cant see the face of who they wrong. And thats even assuming they see file-sharing as "wrong" to begin with.

Like it or not, this guy is accurately describing the current landscape as a whole. This is what content production companies have to deal with.
