The physical medium is the key. The CD serves to identify the correct/original/authorized/licensed/whatever copy. If you can't identify the original, then actually you can't sell it (in the sense of it's not possible).
In the case of the physical CD example, yes. But in the case of iTunes, there is no physical medium to be the key.
Personally, I can't see this company working unless they can hook into iTune's servers and de-authorize the Apple account from having that song, and I don't foresee that happening at any point.
It doesn't, but it's more the fact of "removing your license to re-download the item".
Given that this particular attempt at DRM could probably be defeated by right click+copy into the same directory before "selling" the track, deleting off the local machine does absolutely nothing.

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?
Can possession of the CD really be taken to identify the owner of clear title to the license? What about when someone breaks into my house and steals my CD collection - they can steal the physical media, but the license is intangible - they can't steal that, so I should still own it.
