Imagine saying you can remove Law when he’s more important than most SHs in the overarching narrative lol.
He isn’t though.
The entire narrative leading to Wano is present with or without Law, through Momonosuke. Take him out, and what happens?
-The Strawhats still go to Punk Hazard. They still get into a fight with Caeser due to what he did to the kids, which puts them on a collision course with Doffy and Kaido. They still meet up with Momo and Kin, who setup Kaido.
-they still go to Dressrosa, only to rescue Kanjuro this time. Dressrosa happens the same way, because Law was irrelevant to the actual island of Dressrosa. The Riku’s still provide the antagonism with Luffy
-they go to Zou to meet up with Raizo. Luffy still says he’ll kick Kaido’s ass for Momo.
It’s pretty easy to see how the arcs would have flowed without Law, because Law was not planned. Literally the only difference is Big Mom being thrown into Wano, where she didn’t belong, entirely to get rid of her. And there was zero connection between Big Mom and Law. They had no story together prior to their fight. Oda could have had the Strawhats minus throw her off the island and it would have more buildup, at least half of them were on WCI.
He’s not even important for the future, he’s just strong male Robin who can’t actually read Poneglyphs.
I can‘t remove Chopper because he’s good merchandise and that’s pretty much it.
Remove Chopper and the arc of Drum doesn’t happen. And pre-skip, when we had a much smaller, more focused cast, is entirely changed.
Law’s just one part of an entirely bloated post-skip cast, and an easily replaceable one.
As for Kid, he’s just a non-entity story wise.
