Yeah that was when his goal to only become a normal pirate... THEN he aimed higher and said “I will stop asking you to be in your crew, I will make my own crew, surpass you, and find the greatest treasure One Piece” and that’s where Luffy’s dream was established in the story... and that’s when Luffy’s role as captain cannot be changed
With WB, he lived his life only dreaming of family, never desired any other treasure, not interested in one piece, not interested in power, not interested innany materialistic stuff... it’s foolish to compare the two... I’m astonished you still want to argue when it’s clear as crystal how different they are
