I'm quite sure too that the cloak/mode/form he used against Kaguya requires chakras of all 9 Tailed Beasts, with it being a 'pseudo ten-tails jinchuuriki mode' of sorts. So he either doesn't have chakras of the other Tailed Beasts, with them having been spent on undoing the Infinite Tsukuyomi, or he just doesn't have enough anymore to use it.
