I don't see how that changes the issue. The Ring certainly helped Bilbo execute his plot, and maybe he wouldn't have dared to do such a radical thing without invisibility, but the fact remains that he wasn't going to take Thorin's attitude lying down. As for the Ring's hold over Bilbo - what does that have to do with anything?
