I've seen it repeatedly brought up that Yamato can't join the Straw Hats since invaders may come to Wano and even take its Ancient Weapon. But then where does that leave Jinbe, since Fish-Man Island not only also has its own Ancient Weapon, but also has been invaded in the past by invaders coming to kidnap fish-men and sell them as slaves?
Fish-Man Island doesn't even have Big Mom's protection anymore, so again, where does that leave Jinbe's standing?
