Because people often believe that they are right and no one else is. People also think that once they make an edit that it belongs to them. They don't bother to take the time to understand that a wiki is owned by the community and not any single person. In other words, they want recognition, and they feel that recognition is invalidated when someone reverts their "contribution" no matter how trivial it is.

Unfortunately this type of behavior is always going to happen in a source of information that is open to the public. It's the nature of the internet. If I had my way I would only let registered users make edits.
