My speculative two cents:

- Here is the panel in reference for those who haven't seen it. I interpreted what Kakashi said to mean: "There's no cancelling the effects of it, [because the partner has no idea when the jutsu starts and can't react quickly enough to dispel]". I don't think he meant that the jutsu couldn't AT ALL be broken by another person. I think he instead meant an external partner simply isn't synchronized well enough to the victim to react as soon as the genjutsu starts.

- The one thing that remains constant in the series, however, is that any other kind of genjutsu can be dispelled by a partner. I understand that Tsukuyomi is high-level, but why would it be any different? It would seem to affect the victim with the same basis as any other genjutsu--through altering the victim's chakra flow. There's no reason and nothing to even suggest that the jutsu itself is impossible to disrupt.

- On top of that, Kakashi's word isn't Word of God and from his own circumstances, he has no idea how Tsukuyomi affects a jinchuuriki i.e. someone who has a symbiotic partner. We have what Naruto says about Tsukuyomi ONLY because he got it from Kakashi, who could NEVER EVER have known how easily and quickly Killer B dispelled Sasuke's G:MS when any other solo opponent surely wouldn't have.

- All of this leads me to believe Kakashi may simply have been wrong about Tsukuyomi's effect on jinchuuriki--causing Naruto to wrong as well, if only his intent wasn't to warn about the possible damage done by Tsukuyomi. Because Kakashi COULDN'T EVER have known about the "symbiotic" advantage against genjutsu, he completely messed up how other characters perceieved it.

- @Asian Sasuke didn't have MS yet in his fight with Itachi. Hence, per Zetsu, I believe powerful sharingan user can break out. I also believe a jinchuuriki who has mastered their beast can break out.
