People meme about it, but there is a legit chance that Buggy will become Pirate King whether they like it or not. As far as we know literally all it would take for him is to stumble upon the One Piece first/be recognized to be the one to have done so and it is a wrap.
Oda likely made Luffy have a secret dream unrelated to the Pirate King title for that exact reason, so people can cope and say “w-whatever, not Luffys REAL dream anyway!” once Buggy becomes King.
All agenda aside, Buggy's whole gag is falling upwards and getting into increasingly more powerful but thus also desired and hence dangerous titles for himself.
People said he would not become a Yonko after becoming a Warlord since Oda respected the title so much to "waste it" on a gag character like Buggy. Well, he is a Yonko now. People are saying "no chance Buggy becomes Pirate King, Oda respects the title to much" are just repeating the mistake of the past.
Namely believing Oda would hesitate even for a second to say "fuck everything else, that shit funny!" when writing.
Hell, while I fully expect him to not ACTUALLY take control of the WG like Imu does, I fully expect Buggy's ass to somehow end up on the Empty Throne too just so people can have a laugh about him becoming King of the World.
