Ma's and Pa's genjutsu only worked in an enclosed space and even then it took twenty minutes to take effect. It isn't realistic vs full powered Nagato.
Frog katas can do nothing because Nagato is in one body which means he has numerous ways to stop Naruto from hitting him-- so he can go right on using preta path.
I might say BM Naruto>Nagato IF Nagato did not have preta path, but he does. Naruto's raw power is useless before preta path... with all of his powerups he still can't beat Nagato because he hasn't learned any useful techniques (or smarts), just really powerful ones that amount to little advantage.
The only difference between KM Naruto that got wrecked by Nagato (along with Bee I might add), and BM is that now Naruto can do full-powered TBB. That destroys CT, if that because preta path gets in the way. Naruto still does not have the skill necessary to beat Nagato.
You do know that Sm clones fight alongside, Km clones And Bm mode naruto right in an actual fight. nagato would get wrecked by it as long as Km clone naruto can provide distractions which they can easily do.
It doesnt take that long to perform the genjutsu, and there are clones that can occupy nagato's time.
Ma and pa ccan even use this which is instant and can delay nagato and we have seen naruto's speed with just that much time he can land a lethal blow

Also he can stab him with a shuriken, Who said that ninjas cant use weapons against him, and naruto's speed is enough for him to easily get close and stab him and such ith either naruto himself or km clones.
nagato with his summons can't simply take on Bm mode + 10-11 kkm clones and Sm clones, he will be simply overwhelmed. naruto has more than enough techs to counter nagato's
he will not simply avoid the onslaught of sm clones that naruto can muster, he can use shinra tensei then he is open to attack and then he is screwed. and naruto alongside this can use km clones to help distract. Naruto's summons take can take care of nagato's summons and then goes his shared vision and he is pretty much screwed after that.
Stop overrating nagato, u do realize that once his shared vision goes away he can even get hit by ninjutsu techs one such example is this

he was also easily hit by totsuka once his shared vision went out which he could have shinra tenseied but due to his lack of shared vision he was taken out

kabuto also mentions it

And summons that nagato has can be stopped by a km clone and naruto's summons. add in ma and pa and they will wreck as i showed u already they have more basic genjutsu also other than the one they showed with jiraya.
