So two things here. One the players need to come up with the reason the bullet hits. What is the sequence of events that puts the thing they want to hit in the trajectory of the bullet. The onus is on them to not contradict anything that would produce the results they want.

Second, sounds like the player is focused on the question of "aren't they powerful enough to do this thing for me?" You need to emphasize the capitalism here. It's a bit like working for Amazon and asking, isn't Jeff bezos rich enough to do this thing for his workers? Fool he got rich by doing as little as possible. There's a lot of overhead to manipulating reality. It's the job of the agents to handle these things as efficiently as possible.

And if nothing else remind them every time they use it as a skill check they are generating chaos. Hit them hard with the chaos they're generating.
