The problem here is that you're thinking like a good, kind person interested in legitimate discussion.
Consider this from the POV of a person who is actively trying to get a rise, stir up drama, or derail a thread. Knowing who has the most warning points could help give you a better target to achieve that goal.
Also, I know that my gut reaction would make me more likely to hit the "Ignore" button on someone with lots of warning points. I also know that's really not the intention and/or how the mods use them, which makes it kind of a gray area that I know I might fall into.
