Literally is, explicitly. Obviously not 100%, but no one is saying Loki too would be 100% about his fruit.
Hell, he has 2.6B without the fruit.
Bascially the same. Even BB chose to move to take her Power and It was said the Kuja were know to leave statues of men all over.
Exactly.
Bounty are based on the danger and strenght the criminals have, which in case of DF users It highly related to their DF Power.
It isn't. DF is mentioned as a highlighted strength of Crocodile's, something he possessed when he had 81 mil. Same with Boa Hancock, the WG feared her but only gave her a bounty of 80 mil despite that. Again, Bounties are never given for somebody simply possessing a special DF. Luffy, Law, Boa, countless have all proved it. They're always based on events the WG believes the characters accomplished or the total prowess gain they now have after some years.
Luffy had gained a bounty of 1.5 Billion, the WG was not sure about what specifically Luffy's DF was, until Wano. Yet what happened?? Luffy was actively using his DF in front of Marines long before that. Usage of the DF has no correlation to IMU or Gorosei being aware of it being that specific DF. Unless your claim now is Luffy did not use the nika fruit before Wano, then by all means go ahead.
Loki fights a top tier or two with his DF, but the marines only see them in his hybrid form or base form near the end of the battle... are you gonna claim the DF has no factor in it? Hopefully not.
Related to DF power is not based on DF. The DF power is a tool that factors into the event created by the character, which has nothing to do with my OP.
