You're not "taking" the same thing - the physical CD manufacturing process weighs heavily into the price tag, and the artist actually gets very little. For that reason, so-called "new marketing" is far more important in music than anywhere else - and this is the real reason behind the RIAA's actions: to protect the absurd profits of the labels.

That doesn't mean stealing is 'right' or even morally ambiguous, but it does mean that the tide is shifting away from what you're talking about and toward a new music model. There is no reason to support the "old" system any more than there is reason to buy dictaphone recordings or fly in an autogyro.
