So why didn't I see in Dressrosa say that Zoro was almost twice as strong as Sanji since he had almost twice thebounty? I also didn't see anyone say that Usopp > Sanji because he had more bounty.
You accuse the Zorotard, but you should look at yourself in the mirror first.
It has long been known that rewards do not represent strength, but rather dangerousness. Knowing King and Queen, I think King is not bloodthirsty and his bounty if it represents his strength. And no, they don't take the Lunarian issue into account. Whether the government knows it or not, it doesn't matter, because they don't want to make it public. If not, everyone would know. What minimum would be 100 million extra.
On the other hand, Queen is a sadist, I think it's easy to assume that he has experimented with his biological weapons on civilians and that raises the bounty`s a lot as it happened with Kid.
Also, that you have to take this bullshit as an argument for parity between King and Queen just goes to show that they're not. King proved superior to Queen in everything and Queen was defeated in the most pathetic way of the entire manga.
