First off, the argument of no Kurama inside Naruto. You need to realize that there is not and will not be a Naruto without Kurama, such a thing doesn't exist. Saying no Kurama for Naruto is like saying no Sharingan for Sasuke or Byakugan for Hinata.
Second, the argument that Naruto's huge chakra pool comes from Kurama. Uzumaki's have always been the host of the strongest Bijuu, Kurama, for a reason. They have incredibly crazy amounts of chakra, as shown when both Kushina and Nagato were able to incredible feats like destroying avillage or restraning the nin-tails while in bad health conditions. In fact, having a bijuu takes away from the host's chakra, since the seal requires chakra to stay in tact. This also means that not EVERY single person can become jinchuriki's and only a select few can, which is shown in the case of the Shukaku and Gyuki.
Thirdly, I'd like to address Naruto's non-Kyuubi related abilities. Naruto's incredible healing powers were thought to be thanks to the Kyuubi, but it's from his own clan's abilities. Naruto also has Sage Mode which is no small task to master, and is able to go from 1 to 1000 in an instant. He also mastered Rasenshuriken & Rasengan, both being variations of the Bijuudama. As if that's an easy thing to do. Along with his toad summons, he's also great at utilizing his clones for various purposes, such as in his battle with Pain where he threw himself at Pain using clones.
Fourthly, Having no Kurama would mean his parents, or at least his father, would be alive, meaning he'd be taught a lot of techniques by Minato and Kushina, including FTG and several sealing techniques. It would also mean he wouldn't have such poor chakra control, and would be able to learn at an even faster rate than he already does.
Finally, Naruto without Kurama is a weak argument from (X) Fanboys, and they forget that Naruto had to EARN these abilities, Kyuubi mode and Sage Mode, by training in life-threatening situations, and it wasn't easy too. He earned his powers unlike many other characters.
