Rand believes in force. Remember Ragnar Danneskjöld, the philosopher turned pirate?
Rand doesn't believe force should be used to create a utopia. She believes that force should be used in self-defense when it is rational to do so - and this includes defending your property from collectivists. So basically she believes it is morally acceptable to violently defend your property from tax collectors, as long as in doing so you are not sacrificing some greater good such as your happiness and well-being.
