But if I can identify the original file given to me by iTunes, in the same sense that I can identify the CD, why can't I sell that original? Because of what I may/can do?

To ask it in RIAA parlance: If something gives me a license, should I not be allowed to sell that something?

And if you would answer no, I'd ask why can't I sell the CD?
