I agree with you on that, that a permanent source is needed to continuously generate x chakra, hence why I think it was Hashirama's cells responsible for Sasuke's Rinnegan. But Hagoromo still gave them some power-ups regardless. Excluding the limited time seals, Hagoromo 'gave' Sasuke his teleportation technique, while to Naruto his Six Paths Senjutsu. So even though I agree with you, Naruto still has Six Paths Senjutsu years later, without having a physical part of Hagoromo inside of him... so it would seem Naruto was permanently altered by Hagoromo's chakra? Unless Hagoromo simply taught Naruto how to use it in the mental plane or something...
