"How does Naruto's fight with Toneri have anything to do with Sasuke? "

Because Toneri's moon cutter couldn't scratch Naruto in a weakened BSM form, and Sasuke has durability equal to SPSM Naruto from the Boruto movie. Rinnegan Sasuke's durability = SPSM Naruto >>>>> 4th War Naruto = Sasuke >>>>>> Full power BSM > Weakened BSM

Nagato literally can not put 1 scratch on Sasuke unless he has a technique that is stronger than Toneri's sword that cut the moon in half. Nagato's Chibaku Tesnsei (His most powerful technique) was blow up by Bee's bijudama + some extra help. Nagato's most powerful technique literally wouldn't scratch Rinnegan Sasuke. This fight is one sided.

"how do we know letting kurama fight outside of naruto weakens him?"

Because Naruto's BSM chakra mode, is powered by a fusion of his and Kurama's chakra. Kurama was let out the seal, and was using his power to fight Toneri's golem. All that power that Kurama had, Naruto didn't because he wasn't in the seal to give that chakra to Naruto.
