The Recognition That There are Limitations on The "Do-No-Harm" Freedoms: We are prepared to accept limitations to our freedoms for many reasons, not just that of public order. Take an extreme hypothetical case: public exhibitions of necrophilia are quite rightly not permitted, though on Mill’s principle they should be. A corpse has no interests and cannot be harmed, because it is no longer a person; and no member of the public is harmed if he has agreed to attend such an exhibition.

The Belief That We Should Not Stop Fighting Particular Crimes, Even if We are Not Always Successful: It is of course true, but only trivially so, that the present illegality of drugs is the cause of the criminality surrounding their distribution. Likewise, it is the illegality of stealing cars that creates car thieves. In fact, the ultimate cause of all criminality is law. As far as I am aware, no one has ever suggested that law should therefore be abandoned. Moreover, the impossibility of winning the “war” against theft, burglary, robbery, and fraud has never been used as an argument that these categories of crime should be abandoned. And so long as the demand for material goods outstrips supply, people will be tempted to commit criminal acts against the owners of property. This is not an argument, in my view, against private property or in favor of the common ownership of all goods. It does suggest, however, that we shall need a police force for a long time to come.
