We should, but it shouldn't be stated as a fact because, frankly, Kakashi doesn't know what the hell he's talking about. Something like, "Kakashi speculates that Naruto gaining the ability to float stems from his access to the Six Paths Chakra, after watching Madara and Obito achieve similar feats." That is much less speculatory (because it is important to realize that Kakashi is speculating) and documents what we've been told.
