We don't actually know why Obito didn't suffer from blindness, so everything you just said about it is a good theory at best and not actual facts. Please don't try to word it as facts, because we'll have lots of people just reading that and taking it as facts.

And to be fair, we've never seen any healing technique restore sight to a blind Mangekyo Sharingan. Healing Power (which is said to be a product of Hashi's Cells) didn't even restore the vision within the blind Sharingan within Danzo's arm, so I doubt CR or the BS would do so.

Another thing, Naruto restored Kakashi's missing eye completely, but couldn't completely restore functionality to Guy's leg after healing it - Some things just can't be healed I guess.
