Whats interesting is that rocks D xebec never wanted or tried to be the pirate king. I don't think he even looked for poneglyph to try to find the last island to be pirate king. Idk whats his true motivation to why he wanted to rule the world but he had different completely goal compare to roger luffy Bb etc
when you even think about it IMU had all these 800 years to look for the one piece but they didn't and they don't even care that luffy is Nika or joyboy. Imu and the world government are just watching and waiting for another joy boy/nika to try something again.
my main point is that
is there another hidden treasure or hidden power that rocks knew and could challenge imu and the world government without needing the pirate king treasure ?
Like there is another method of not needing the pirate king treasure to challenge the world government
1 method = IMU power
2 method = pirate king treasure
3 method = what rocks had or tried to get
