@LegionZero- Naruto's chakra mode became Naruto's Kurama mode because Kurama wanted to help Naruto and the seal was obtrsucting the chakra supply, after Naruto removed the seal he fistbumped with Kurama and shared his feelings, I think the fistbumped formed a permanant link, he also fistbumped other tailed beasts and that is why I think he became Jinchuriki of them. The chakra he gave to the alliance is converted to suit every individual, he could take Kurama's chakra and convert it into his signature so that is why the alliance is not a jinchuriki of Kurama (if you get what I mean). Obito didn't have tailed beast chakra because Madara sealed the tailed beasts into him and he became the Ten-Tails Jinchuuriki, Obito had Yin Kurama (because Black Zetsu absorbed it) and Gyuki and Shukaku (from Madara) then he transferred it all to Naruto that is why he didn't have their chakra after the transfer. Hagoromo said that he is the link to all tailed beast, he is a meeting place because he has chakra of all tailed beasts.
