Yeah, like the biggest events in the world have not been Marineford, orchestrated by BB, pushed by Sengoku and involving WBs where Luffy is basically an afterthought.
Or Akainu vs Aokiji.
Or BB having 3 Poigne Gliffe.
Or Shanks vs Kidd.
For being a shonen, One Piece is one of the few where NOT EVERYTHING is about Luffy.
Hell, WCI was about Vinsmokes and BM.
But sure, go ahead and push this fake narrative.
Sure Luffy wasn't the biggest factor in the cause of the Marineford War, but Ace is Luffy's brother so he had to be involved in that event somehow. Luffy was the decisive factor in the Impel Down escape, which BB needed to qmo up his crew to enact anything else.
Shanks vs Kidd was only possible because Luffy carried Kidd's ass in Wano.
Blackbeard having 3 Poneglyphs was only possible thanks to Luffy's victory in Wano, and his underling Robin making copies for Law and Kidd, which were stolen by Shanks and BB soon after.
Honestly what was so huge about Akainu becoming Fleet Admiral? He hasn't done shit, only sitting behind his desk the entire Timeskip.
Most of these situations needed Luffy as a catalyst to even happen, and most of the other things are rather insignificant in comparison, and are usually waiting for Luffy to do something to actually make any impactful moves.
