I've always argued that although the odd fight can be entertaining, watching them argue and fight all day long will become very boring. Part of the reason I watch the show is to see how people interact, watch friendships grow, see how people react to certain things, etc. Fighting is only a small part of that.
Also, when the house is in a permanant state of chaos, you don't get to see any real personalities, people like mary will hide in the corner, along with saskia, etc. It becomes about the loudest and most opinionated housemates, which is even more dull.
