Yea i find this the most likely. Momoshiki and Kinshiki were a greater threat than Kaguya. Why? well according to this episode, because they could alert the entire Otsutsuki homeworld to the fact that the Shinobi world rebelled. Two people who ate those pills were already extremely annoying, imagine if a squad of 20 Otsutsuki princes arrived, each with Rinnegan and Byakugan and just started attacking all over the world. Not even Kaguya could stop that.

At least if she had Zetsu she could attack the Otsutsuki themselves and so create a diversion.
