The reason the World Government might have changed name isnt because its some hax overpowered fruit, but because it might have previously belonged to JoyBoy/Sun God Nika. They want to eliminate JoyBoy from history. Hence why when a guard in ID spoke about Nika, he was never seen again the next day. Luffy having the fruit is evidence Joy Boy existed lol
