While your point is right but sometimes we gotta see that is there even a growth to acknowledge in the first place or we all gotta just acknowledge so called fans headcanon and if not so then we're labeled haters which obviously isn't the case
Majority of arguments are here stated by the possibility of one specific character being able to achieve a level which one cannot hope to achieve and some debaters are not haters to deny something which yet to happen or never might happen
Fair enough but when reading One Piece that mentality only closes you ideas. Odas always proved us wrong he doesn't just spread ideas since a "x " quantity of chapters for nothing .
You and me should know that Oda always ties all knots for a future purpose none are left hanging unless the moment of it is not close yet.
Plus..
But one must take in consideration what is this character purpose in the story .
Is it one whose end goal will only be happy or simply not strength related?
Is it one whose who will stand at the top?
Is it one with any building whatsoever pointing to what some claim?
That character is far from such(some ppl mindset) but if he's meant to do such Oda will find the proper route , only cuz it's not the MC you can't simply call stupidity.
People just need to chill and accept possibilities that Oda himself planted through the story and refrain from insulting and calling nonsense when the author decided to give such ideas....again all has a purpose.
