Chakra nature or not it is still Kurama's ability which was gained through forcefully taking it and using. I know Yagura had complete control over Isobu point is he didn't get permission. Hmm, your idea of mastered is different from mine as I would never say that about Yugito's level of control but... meh same point as the last ones. Your wording is confusing me on the last one are you saying the Steam Armor would be useless if Han had been able to create steam on his own or that the armor would be useless if the armor wasn't able to create steam by itself?

The training wouldn't have been useless if the only way to use the Tailed Beasts techniques is through completely subjugating or befriending them (which has been proven unnecessary) it would have been pointless if Naruto completely lost Kurama or if he simply never succeeded.
