I have already adressed this counterargument in this thread but:Great argument except the chakra point. His chakra was said to be just like madara uchihas by kurama. madara was the only uchiha to be able to achieve the rinnegan. other than that you have a great argument
"Although Kuruma did make that statement on his chakara, he did not say that his chakara was huge, only that it was more sinister than his own. Plus i would like to state that by feats alone, Sasuke does have elite chakara levels, however his jutsus run through his chakara within minutes. Rinnegan jutsus would only be even more taxing on his chakara supplies."
