I kinda agree with him tho, if i write it it will be like dis:
- Zoro used Asura vs Kaidou at chp 1010, but 2 of Zoro's sword broke upon contact with Kaidou's skin.
- Kaidou said to Zoro, "Scram" and Zoro just froze until Law teleported him outta Kaidou's sight.
- Luffy used Internal Destruction vs Kaidou at chp 1010. Kaidou, for the first time being damaged, finally finds a worthy opponent he longs for his entire life. Flashback about Joy Boy here. The battle spans for 3-4 full chapters, but Kaidou uses Awakening and put Luffy at death's door.
- Joy Boy is actually Kaidou. The Strongest of All Living Being. but he is suffering from the prophecy due to something important in his life.
- Luffy reaches an enlightment from the way Kaidou uses his haki, and invents a power unique to himself, for example "Conqueror's Internal Destruction being stacked upon one another" and finally beat Kaidou.
- So Luffy surpassed a legend, becoming a legend of his own effort instead of being a chosen one.

But if Luffy just need a single powerup and its enough to beat Kaidou, it will also make some cult dissatisfied
