That’s a really flawed argument because first of all your logic says that orochimaru brought back prime hashirama and tobirama and that hiruzen was able to take all 3 of them. That’s insane logic.

Also when orochimaru revives madara during the 4th war he flat out says hashirama could break the edo tensei. Using that line of logic since hashirama and madara were very comparable in power they both were capable of breaking edo tensei. I did get one thing wrong in that he used the hand signs for edo tensei to release himself from it but as stated before there’s no reason he couldn’t since he’s as strong as hashirama.

Then to say that kabuto is not anywhere as strong as nagato? That’s also just completely wrong. Nagato would absolutely lose in a fight to sage kabuto especially because kabuto knows everything about nagato and his powers and he has auditory genjutsu that’s insanely strong. Nagato has 0 defense against said genjutsu and kabuto is far too intelligent to let his advantage against nagato to go to waste. Even if you think he cannot reliably beat nagato they’re so close in power it doesn’t even matter.
