To be fair, this example doesn't work because those chip bags are two physically different objects that one can consume.

Sony is trying to argue that because they are selling digital copies, that consumers cannot be granted rights to their copy because they can't transfer the intellectual property rights, which is complete nonsense. I have a 1999 DVD copy of The Matrix that I have owned for 27 years, and short of the physical disc-rot, I will be able to play that DVD until the day I die, and Warner Bros can't do anything about it unless I try reselling new copies, or claiming authorship because, despite owning the disc, I do not own the rights to the movie...

A download isn't any different just because it lacks a physical form.
