Ummm, Levy pulling the book out of nowhere and all the other stuff is solid proof about how the Nakagami Armour works. After all, we assume that Mira's hypothesis that Abyss Break requires mastery over all elements is correct despite the fact that the Giant was still casting it even when deriving its power only from Aria. No matter what one's personal opinion might be, what is stated in the series will always take priority over what we think. So I say that Erza is incapable of using Nakagami Armour in her present condition. No complaints there.
