We never interacted with Naruto, yes I get that we aren't showing up and just swear fealty to him, but just trusting him (as a Clan head) after all that happened because Jiraiya did, without trying to get to know him? That's a wrong move, let's get to know him for a while and then decide if giving him any further power (beyond Hokage) is a good idea.
Jaraiya trusted him, and I trust Jaraiya. I'm not going to gainsay his one direct request to us. No, this doesn't mean "if Naruto is a massive blithering idiot, do nothing about it" - it means cooperate,
but keep the insurance letter Jaraiya wrote us. He's deliberately given us the weapon we need to effectively dispute Naruto's claim to Clan Head if need be.
Not only that, but do you
really think he wouldn't have noticed the potential power of the Uzumaki seat? If the "two seats" plan was
actually better than adopting Naruto, would it not be
better for Naruto as well?
Jaraiya is actually competent and looks out for those he cares about. He would not deliberately steer us into political danger by costing us a vital seat on the council, and I would bet you a dollar that there's something in Naruto's letter about the disposition of the Uzumaki seat.
And if you're saying he was emotionally compromised: Sure! He was probably emotionally compromised! But do you really think for even a second that he would
deliberately put Naruto in danger by making him head of a clan he wasn't ready to lead?
Jaraiya knows Naruto, and he knows us. He's also a S-rank master diplomat. I think it would be a
serious mistake to ignore his final request to us.
Jiraiya made no comment to this effect. Additionally, he said it was an option for Tsunade (the only Senju -- QM confirmed) to assume her seat on the council. So there's precedent for one-person clans being legitimate.
The question isn't about whether the
Uzumaki are legitimate, it's about whether the
Goketsu are legitimate. Additionally, I would like to note that this means that Jaraiya knew that we might need every council seat we could get, and
still advised us to adopt Naruto. Do you
really think that the Uzumaki seat just slipped his mind?
