Yea but what that has to do with what I said?
Because you believed a hype title over the reality of the history of the one piece world. Kaido was really strong, but he's not a power cliff.
The pirate who pretty much just hung out with his family until they tried to execute his adopted son and then failed to save him was not actually currently the strongest man in the world, because he lost. He also got fucked up by a ton of different people in that fight. In his prime? Maybe the strongest pirate but he still wasn't fighting the government.
The guy who acted like the world government's dog under Orochi and only decided to try being a pirate again when his old crush showed up is not ACTUALLY the strongest, or he would have tried to fight the government himself and actually tried to become Joyboy like King wanted.
The WG thinks they're gods above the world. Of course "World's Strongest" can be below them.
