On the flip side, Theoretically I could go and get a gmail account and then new ITunes/Comixology/etc. accounts, and the purchase an entire run of a comic series under that account. Then remove or cancel the credit card from the account and sell that complete run (complete with the login and password). Now that's a big huge pain in the ass, but I've managed to sell the digital comics. Even though I didn't own them. Thus ownership and the ability to resell are not related.
So if people don't like DRM-protected stuff, that's fine. If they don't like the fact that it's functionally impossible to resell it, that's fine. But not owning the stuff, in and of itself, is meaningless. And that's not an issue of "why do you want to own it" - it's a matter of "how does owning it provide you with an ability that can't be taken away from you in some other way."
