It's still don't matter lol. I'm not saying that he'd be respected as a Pirate King of he were to take the route I mentioned. I also didn't say that he wouldn't get crushed after obtaining the info to Rafael and whatever is in that place. I simply said that to HOLD THE TITLE of Pirate King you simply need to reach Raftel. Sure he's going to fight all the Emperor's and deliver a final blow but that still doesn't make him stronger. Just like beating Doflamingo didn't mean he's stronger than him can we atleast agree on that? Sure the Yonkou that "loses" won't be attacking Mugiwaras again since that's how the plot usually goes, but unless Luffy gets a Power Up the size of an Ancient Weapon then he'd likely never be the strongest character in One Piece even after obtaining Pirate King TITLE.
