Speculations Two Options For How Luffy Can Finish the Series

Two Options For How Luffy Can Finish the Series
I'm going to throw it out there that the story may ultimately end in two ways.

A) Luffy lives, and rules over the recreated Ancient Kingdom. Everything stays the same, except the Celestial Dragons no longer oppress anyone. (World Prosperity)
B) Luffy dies, and the world "goes back to normal." without any Devil Fruits or anything like that. (World Liberation)

Any thoughts on this?
It could happen to the entire world.

He might become World King just because everyone else demands it and won't accept a no for an answer.

Just like with the Grand Fleet.

It would be in direct contrast with Imu who rules it now but nobody would accept it if they knew of it.
