also sasuke did not get the Rinnegan because of hashirama's cells. Like i said: Hagoromo took what was already there, and used it to give them power. Sasuke has a Rinnegan because he can naturally awaken it. But as we've seen with Madara, that takes decades. We have no idea how one awakens SPSM naturally, but we do know the mode is essentially an inferior Juubi mode. Hagoromo simply facilitated either mode.

Chakra gifts always run out. Never has a chakra gift been able to transfer powers, never has it regenerated. The only logical conclusion is that Naruto and Sasuke are naturally able to sustain their power. What Hagoromo did to Naruto and Sasuke was the exact same thing he did to the Juubi: he simply manipulated what was already there.
