Hagoromo gave Naruto and Sasuke SP chakra that, when combined with SM and EMS respectively, form SPSM and Rinnegan. Just because you activate a new form or mode does not mean you can produce that chakra to utilize that mode whenever you want. If that was the case then Naruto can constantly produce and use NE and SM even if he wasn't a perfect Jinchuriki since he activated it before. He can also create the chakra of all nine Biju since he received and used their chakra to create his own cloak in SPSM.

Assuming what you said is true about the chakra gift only being there until it was used up, then why wouldn't Hinata still be able to use the Hamura chakra to activate Tenseigan. She hardly used all of it to destroy the Tenseigan Altar seeing as she received all of it (that is like Biju levels of chakra). The only reason she needed Naruto's help to destroy the Altar was because her Gentle Step wasn't destructive enough and Plot no Jutsu.
