Don't forget Sakura as well. Without her Byakugou chakra, Obito would've been unable to open the portal to rescue Sasuke, leaving him in the sand dimension until Kaguya desides to kill him there. Also, it was Sakura who blocked the escape route for Kaguya from above to let Naruto/Sasuke finally touch and seal her.
