Obito and kakashi are both able to use the kamui in the same exact way.
at first it seemed that obitos eye was only able to transport himself and anyone he was in contact with. Making it imperative for him to touch someone in combat in order to transport them to the other dimension. (as we see when he fights minato, saves sasuke, tries to make physical contact with naruto/konan and anyone else he wished to teleport with.)
But as we see on chapter 595, pages 12-13, he can obviously use it outside of his body, when he cancels out kakashi's attempt to kamui the head of the gedo statue.
Kakashi is also able to use obito's way of using kamui, as seen when kakashi teleports himself back to the real world from the kamui dimension.
So since obito was able to do the same thing kakashi was, the question at hand is: Why didn't he use this tech in the first place?
He could have captured anyone he wanted. he could have captured all the the jinchurikis by himself with no help. find them, kamui their whole body into the dimension. wear them out in that dimension by starvation or fighting or w/e, then extract. do them one by one if he had to.
Instead he goes through a ridiculous amount of effort to get them. So unecessary.
