Luffy loses in chapter 1014 and comes back to fight Kaido in 1025, he had 11 rest chapters where he actually rested while Kaido fought Yamato. Then he loses in chapter 1043 and in the next chapter he is already fighting Kaido. And when Big Mom attacks Luffy, his attack doesn't even have any...
While Luffy was recovering after losing, Kaido was spending his stamina fighting Yamato, not forgetting the others who fought before and alongside Luffy. Not even you would believe that Luffy would be able to defeat Kaido in a fair 1v1 fight.
There are some people who like to know that Luffy is the chosen one, that he has no merit of his own and is a puppet of fate.
There are others who have not read critically and have not noticed inconsistencies.
