User blog comment:Ricizubi/Luffy's Evolution and why becoming pirate king is going to be quite a storytelling challenge/@comment-7606564-20180420165932/@comment-3986064-20180420171607

Well kind of. My position is that although it might be inevitable for Luffy to reach that level and surpass it over these next years, it would not be the best solution for the story.

There could be another way in which the story ends - without having the main character get some unreasonable boost in power just for the sake of making him the strongest guy or whatever. His ability to inspire people has already proven the point, especially in Marineford, where he, a rookie, was able to fearlessly lead the charge to saving Ace.
