Loda loss control of the manga.
Why tf would gorosei not go kill all Yonko if it was so easy?
The three power stuff has no sense
Because its literally been established for 2+ decades that the 3 great powers is a facade created by the WG to keep them on top of the world.
The way the WG stays in control is prevent the world from revolting against and rejecting them, not 3-4 powerful pirate crews.
Its abundantly clear where this story is going too when VPs message gets out, much of the world wont be on the WGs side any longer, and the concept of the 3 great powers is going to crash and burn when:
- The Marines (i.e. Akainu) potentially turn againsy the WG for their own agenda after this arc.
- The Shichibukai are already abolished since the Reverie
- The Yonko are no longer replaced when someone finds One Piece
