Naruto received Six Paths Chakra DIRECTLY from Hagoromo. Did you forget that chapter/episode already?

That is why the form that Naruto was in that let him kick back a TSB of Madara's is called SIX PATHS SAGE MODE because in order to use it requires SIX PATHS CHAKRA. Naruto later obtained the TSB by accessing the chakra of all the Tailed Beasts.
