I'm not saying he's permanently lost it forever. I'm sure that if Naruto wanted to, he could go around collecting their chakra again.

Secondly, if you look at the context, it's clear Hagoromo says it so Kurama has an excuse to go back to Naruto. It's not a super-strict absolute rule that Hagoromo imposed. this was also before Naruto actually fought Sasuke to his limit.
