It is really hard to be into this narrative. If he is forced to adapt to danger, he needs to sense the danger and be careful what's coming, not just being extreme stubborn. In this case, it just likes he know he is the chosen one by Oda and that's why he can be like this. He can tank 200 blows from Katakuri or Ragnarok from Kaido if he wants to. He can imitate future sight, aCOA, aCOC in no time if he wants to. There is no other character got this special treatment. Even Yonkos who were hype so much are gonna turn into another Piccolo. Or Zoro, who Oda cherishes so much, needs to admit defeat or accept his limits.
Replace Ace with Luffy, do you think Luffy will be kept immobilized in Impel down? If not and you foresee Luffy turning impel down into training camp getting new skill, it means you understand plot armor I mentioned.
