i hate to sound like a fanboy or any kind of 3 year old defending his favorite character but this is out of hand,
Obito with the Juubi is Obito's Own arsenal meaning it's his power to use.
Obito made the juubi's his own when he Used the sage's seal and sealed the juubi inside of him becoming the jinchuuriki.
Even if he isn't conscious or whatever, it's still his arsenal because if obito lost his mind, then the juubi will be able to escape.
Also, May i remind you that the Juubi got 10x stronger just by being inside of obito?
Other example:
Naruto: Naruto has also been taken over by the kyuubi and Made him lose consciousness many times but it's still naruto's power because he is the jinchuuriki.
Gaara: Gaara went fully crazy many times and could barely control himself while the 1 tail was unleashing his wraith and it's still considered Gaara's Power because He is the Jinchuuriki.
*Jinchuuriki means that the user has taken the tailed beast for himself and is able to use their chakra and strength.
Controlling the beast is another topic because it takes time to control one's beast.
All in all, i hate to sound like a fanboy, but even i thought this was obvious.
