I am utterly infuriated by the attitude that breaking rules is okay. It's all the more galling that our society rewards some rule breakers. When I'm feeling particularly petulant I can sort of understand how one would feel an attraction toward authoritarianism and totalitarianism.
From a realpolitik perspective renting your house to strangers is dumb simply because a significant quantity of strangers are rule-ignoring dicks.
Edit: I am aware service animals cannot be prohibited. Service animals are not pets.
