And I didn't mention a permanent structure. Like kimimaro, his bones can break. It would require a great amount of strength to do so. I discussed this with others, Muzai's Shiko strength (as in bone structure) is on par with other users, it's just that he can create more bones because of his chakra, and make better creations because of his chakra control.
