Just having a strong attack doesn't make one a jounin level ninja. Sure Naruto only needs one hit to finish pretty much any opponent, but he has to get that hit in. Kazuku underestimated Naruto and brashly went in for the kill without considering the possibility of the Shadow Clones being distractions. If Kakashi had tried the same trick on him he would have probably been more wary since he'd expect more danger and trickiness from him. If Naruto was treated like a true threat by an opposing jounin level ninja I don't think there are many that would lose to him. All they'd have to do would be move faster than him and kill him quickly with a kunai to the back of the neck (come to think of it....why didn't Rock Lee do that to Gaara?).

Also, where are you getting that Kyubi uses wind chakra? From the thing about his tail waving creating Tsunamis? From what we've seen so far the Kyubi chakra has always been raw energy that can be harnessed for increased strength & speed, or for directly attacking an enemy (Kyubi Claw, Kyubi Rasengan, Kyubi Death Ball). In all the instances it manifested for a direct attack it had a definate shape but never seemed to have any element to it.
