The very worst part is that they keep on trying to counter my point that Pirate King isn't something you can accomplish completely by yourself by bringing up Luffy's innate charisma that allows him to make allies. Lemme restate that again: Their counterargument for Luffy needing allies to become Pirate King is that Luffy has the ability to naturally make allies.
They might as well be going ¨Aaron is such a nice a guy, people like him, so they helped him build that house, so Aaron obviously built the house by himself.¨
Not only that, but it fails on another level as well. I'm saying Pirate King isn't based on your individual strength alone. It's not something you can gain just by having tremendous ability or skill. Their counterargument is charisma, something that isn't an ability or skill, as Mihawk made clear, which goes along with what I was saying: Pirate King is about more than just being powerful; it's not a rank of power.
Obviously becoming Pirate King is gonna be much harder than becoming the World's Strongest Swordsman. Of all the pirates in the world, there are gonna be more pirates who want to be Pirate King than those who want to be World's Strongest Swordsman because only a fraction of pirates are swordsmen, and then a part of them will actually be swordsmen who want have that aim and drive. Compare the amount of people who want to be Pirate King to the number of people who have claimed to want to become WSS. Not to mention the World Government is actively trying to prevent a Pirate King from happening again, so you have their forces on your ass, but they don't care about someone becoming a new WSS.
There's also the fact that becoming WSS has a simple task: Becoming stronger and stronger until you can beat Mihawk. Becoming Pirate King is a bit more complicated, since you have to find One Piece, something that know one has a clue of the appearance of nor definite knowledge of its location. The closest they have to knowing where it is is their guessing Raftel, and even Raftel's location itself they have to guess about.
Shanks is a swordsman, Mihawk is the world's strongest swordsman, the math is pretty simple. The WG have the Shichibukai because the Yonko have allies. They don't have seven Shichibukai and three Admirals to combat four individual Yonko, they have them and their Marine forces to combat the four Yonko and their allies, which number into the thousands. With just five Shichibukai and the Admirals at Marineford, the Yonko Whitebeard's side got a crushing defeat, only one of the Marines' major players suffered close to severe injuries and that was Akainu, and even those didn't stop him from taking on the strongest members of the Yonko's crew after the Yonko died.
