I mean there was a chance to get to see Naruto fight without being a Jinchuuriki when Madara sealed Kurama, too bad we didn't see any action from Naruto.
When Kushina lost Kurama she was able to use jutsu to keep Kurama with chains.
When Obito did Rinne Tensei and lost the Juubi we got to see him fight without the Juubi. We saw him fight without being a Jinchuuriki.
Madara we saw him fight without being a Jinchuuriki and being a Jinchuuriki of the Juubi.
Kishi just didn't want to give Naruto any fight without being a Jinchuuriki.
