I actually liked that thus was handled real well , the reason why Luffy wants to be the Pirate King is because he believes the PK is the most free person in the world and his DF's awakening unlocks that let's his imagination run wild. This chapter to me was even better than the hype also makes me wonder about Shanks , he stole the Gomu Gomu no MI from that CP0 agent years ago and he essentially entrusted Luffy to have it but when he met with the Gorosei it was implied that he talked about Luffy , I don't know if he meant that as a Warning to them to back off or if Shanks was trying to use them to possibly subdue Luffy the whole thing looks murky now.
Also a nice hand in hand piece that Ace then Sabo had the Flame Flame fruit, as now Luffy himself looks to be an embodiment of Fire as the Sun God Nika.
