Friendly reminder that Reanimated Itachi is not stronger than Reanimated Nagato

Itachi found a way out of Nagato's Catastrophic Planetary Construction (CPC) based on Naruto's experience and successfully neutralized Nagato's jutsu because Naruto, Bee, and himself all launched their strongest long-range ninjutsu at it, and after he took advantage of a momentary gap, where he pierced Nagato with the Totsuka Blade.

If you remove Naruto and Bee, Itachi never learns from Naruto's experience on escaping Nagato's CPC, never successfully neutralizes the jutsu, and consequently, never creates the opening to pierce Nagato with the Totsuka Blade.
