Exactly right, Gennins don't have a team, but at some point, they have to learn to lead or else how can they become chuunin leaders in the first place?

That's why I said the idea for this episode was good. Especially the way Tsunade explained it to Naruto. Naruto should been all,

"Bitch, I don't need to learn leadership, the Hokage is the strongest ninja in the village! All I gotta do is beat the shit out of your ass and I get to go straight from Genin to Hokage! If I'm stronger than you, I gotta be the Hokage! Believe it!"
