i still think people are overanalyzing the role of Hokage and not taking it for what it really is:
The main character's stated lifetime goal in a shounen anime.

In reality, Naruto would suck at it, and almost all the important decisions would have to be made be advisers (Shikamaru and Kakashi, that's you). But the show is about him winning recognition from people, which he does despite beign stone-stupid. I don't see why that wouldn't continue.

If he'll ever surpass the Fourth Hokage, or even a jounin like Kakashi, in OUR eyes is another story. Most people would say 'no', due to his idiocy. But I'm still banking on us getting a wildly different conclusion to the Naruto storyline.
