So evidently, some sort of mark still remains even after the Biju is gone. If this is all that is needed for IT (and it's not implied to take a lot of chakra to undo, so it very well could be), then Naruto having once had that chakra would be enough to meet the requirement.

Secondly, Sasuke had all the biju but Yin kurama in his Chibaku tensei, so he could get their chakra easily and undo IT nearly himself. He already got their chakra before, so he can do that. Only Yin kurama is needed, and Naruto has that. If he had defeated Naruto, he could've taken Kurama and undone it himself. This isn't rocket science.

I haven't seen Kakashi produce a chakra shroud, yet he got Kurama's chakra in the exact same way Naruto got it from the other beasts. Therefore, there's plenty of reason to think that it ran out, namely it ran out in every single other case. Nor does he need it for IT. Hell, Naruto's clone got chakra from Kurama, and it ran out. Naruto even mentions this. A Biju can give just chakra, and that chakra runs out.

Also, Hagoromo said he was a meeting place that Kurama looks over so Kurama had an excuse to want to go back. He even looks visibly relieved that Hagoromo says it. It served no purpose other than that. He hasn't been a meeting place since, and if a threat to the entire village isn't enough to be a meeting place or call on the Biju's power, i don't see what is.

Besides, kakashi also hasn't shown Susanoo or Kamui, so he surely still has that, doesn't he?
