Very Great analysis, people love to bashes Toneri simply because they love to pick one of the scene of Toneri being defeated out of the entirety only to use as their argument. What even amazed me is that they even want to neglect other things that Toneri delivered which they don't even bother doing any sort of research like slicing the moon in half, bringing rains of Meteors , bring Golem Hamura to life and was too competent with Kurama, even there are times when Toneri easily screwed Naruto to the corner.
Using "a single punch" as proof that he's weak is cherry picking. It wasn't mere punch. Naruto basically focus all his chakra towards his fist and unleash a punch that knock Toneri severals meters away. The punch was so strong insomuch, it's created a shock-wave which caused a huge crater similar to guy's Evening Elephant attack against Madara.
Afterward Naruto got himself huge exhaustion, all of his chakra is drained, if it were not for Hinata, Naruto wouldn't be standing.
Even Toneri still have his remaining consciousness and still can do more
Honestly speaking Toneri could've easily used all of his calibur to completely overwhelm Naruto if it had not been any distractions when dealings with others at the same time.
Anyway it is something that needs to get off my chest.
