Does Benatars argument fail because he is using conscious terms on a non conscious being?

So I understand his arguments about absence of pain being good and absence of pleasure being not bad.

How can we apply objects like pain to something that isn't councious?

If I said 'that chair is lucky because it's not in pain' it's an illogical statement because luck requires conciousness.

Pain requires conciousness. So how can you apply something that needs conciousness to a non conscious being?
