1. Lets the attendant/owner/manager know that someone won a free game. In a loud environment (arcade -- remember those?), free games can be kept track of without having to wander around and watch every machine.2. Lets other players know how awesome you are at pinball.

Just one more thing to try to achieve, and therefore motivating you to throw down more money.The real question is, "Why do people keep the knockers on home games enabled?" For me, it's mostly tradition. And maybe so my non-pinball friends will ask the same question you did so I can talk about arcades and the old days.
