SeaTerror, I think you are missing the point. What Usopp did only affected Doflamingo in a negative way. Doflamingo does not issue official bounties. In the world government's eyes all he did was knock out a little girl. The world government will never take into account any positives (such as how many people were saved) when issuing a bounty. And finally, Usopp knocking out Sugar isn't that much of a threat to the World Government. Yes, he completely ruined Doflamingo gave him a massive bounty, but that's his personal issue, not the World Government's. Doflamingo issued the bounty because he wanted revenge for undoing all his hard work. The World Government however, issue bounties to those they consider a threat. And knocking out a little girl doesn't really pose much of a threat to the World Government.
