I know this is a bait thread, but I'll play along for fun.
There's nothing wrong with Naruto using Kurama's chakra. The Tailed Beast's power is the Jinchuriki's power. That's how it works.
Also Naruto had to fight and defeat Kurama in order to control his power. He earned the ability to freely use Kurama's chakra. It wasn't "handed to him" like haters constantly parrot.
Thank you for that. I too, know this is a bait thread, but allow me to add my two cents.
Much as it, fair or unfair, to which ever party. Up to the Mangekyou Sharingan Sasuke's power was his own. Then he used his brother's eyes to not only restore his waning eyesight, but to gain his brother's abilities of Amaterasu and Armored Susanoo. Until that point he never had those powers. Debunking your statement where Uchihas keeping 'their own abilities'.
Still the same can be said about Naruto as he wasn't born with Kurama's chakra. Still, unlike Itachi, Kurama gave permission to Naruto to use his power. Also, Naruto trained and mastered use of Sage Mode. He may not produce it like Jugo, but he's learned to utilize it and project it much better than most other masters.
Respectively, Sage/Rikudou power and Rinnegan both are 'gifts' if you will, as they must come to existence through external means. Sasuke received Senju DNA from Kabuto, while Naruto was given chakra from all the Tailed Beasts. Either way you look at it, it's all fair for everyone, because they all cheated.
