I wouldn't go that far. Unlike Pouf, Youpi can't split his cells apart into seperate entities, but simply rearranges them into different structures. The only people that fought him were Killua, Shoot and Knuckle(I'm not counting Morel since he mainly used Deep Purple to distract him), two of which use a Hit and Fade fighting style that isn't meant to damage their opponent; as such, the only real moments we saw his durability tested were when Killua attacked him, when he entered the Rose's crater and during his Self Destructions. Granted, whilst all of those are impressive examples, they aren't automatic proof that he is indestructible. Killua's offensive powers probably wouldn't be enough to significantly any of the Royal Guard, I believe Youpi only stood on the molten rock but didn't completely submerge(correct me if I am wrong), and during his self destruction his anatomy changes so much that I don't think it's fair to compare it to his base form.
