In the same way that tax revenues are not maximized by maximizing tax rates, as per the Laffer curve, freedom of action and opportunity is not maximized by maximizing legal freedom for everyone on the planet. Podhoretz, for example, would not be more free if Hamas were legally permitted to set up Jew-baking ovens in New York City, just as Americans would not be more free if 50 million Mexicans were legally permitted to enter the country and begin voting for the sort of policies they are accustomed to voting for when choosing between the Partido Revolucionario Institucional and the Party of the Democratic Revolution, both of which are members of the Socialist International.
Since freedom is not easily mathematically quantified, it is not as simple to construct a Liberty curve as a Laffer curve, but the logic is the same.
Having the heart of an anarchist, I understand the case for eliminating government. It fails, like all theoretical utopias, when applied to imperfect men in a world open to evil.
All political theories based upon the non-aggression principle would not interfere with Hamas setting up those ovens, and would actually have to restrain Jews who might choose pre-emptive action in perceived self-defense. It seems naive to hope that Hamas could be prevented from fueling the ovens once they were built. More so under a minarchist or libertarian government.
Some slopes are slippery. The art of just governance is balancing the human tendency toward malice with the human tendency toward power.
