well when he was talking to sakura in the kamui dimension he stated that he could only transplant one of madara's Rinnegan because it was far to difficult to use both and that it was still to powerful of an eye it would stand to reason that it would be difficult to do so when being the shinju Jinchuuriki. also maybe he felt he did not need it because he was effectively immortal

No, he said he couldn't warp Sakura and himself back because it was too difficult with the tiny amount of power he had left. It nothing to do with the Rinnegan, where did you even get that??

Like Questionaredude said, the was never any reason given, other than it a excuse for him to weakened for the sake of the plot. That also becomes bullshit after Madara effortlessly teleported while a jinchuriki. So not only is it a half-assed attempt at depowering Obito, it isn't even consistent.
