These ardent anti-statist liberals are of great interest to anarchists, since their analysis does not depend on a monopoly government. On the contrary, virtually everything they have to say can be applied to voluntary security arrangements in a stateless society. One simply has to interpret the word "government" in the broader Jeffersonian/Nockian sense as an association for the protection of rights, rather than in the more common sense of coercive monopoly, i.e. the state. Also, one may have to forgive appeals to the deity in justifying natural law; rationalistic justifications based on empiricism or contractarianism are more convincing to the modern mind, and could easily be substituted.
The economistes improved on anarcho-socialist thought in two ways. As already mentioned, they had a more sophisticated understanding of property. Secondly, they had a much better understanding of law, legal systems, and the production of security. Most anarcho-socialists tended to see all law as decreed law, analogous to their seeing all property as decreed property. Hence, they rejected law lock, stock, and barrel, and considered it an artificial imposition on man. The economistes saw law as perfectly reasonable and natural constraints on conduct necessary for harmonious human interaction. Thus, it was an essential part of natural society. They saw decreed law as a violation of natural law in many cases, of course, but didn't reject law per se.
The law perverted! And the police powers of the state perverted along with it! The law, I say, not only turned from its proper purpose but made to follow an entirely contrary purpose! The law become the weapon of every kind of greed! Instead of checking crime, the law itself guilty of the evils it is supposed to punish! If this is true, it is a serious fact, and moral duty requires me to call the attention of my fellow-citizens to it. - Frederic Bastiat, The Law
Frederic Bastiat (1801-1850) pointed out that law and property preceeded the state, and explained in simple economic terms why property is necessary.
By the application of our faculties to these natural resources we convert them into products, and use them. This process is necessary in order that life may run its appointed course. Life, faculties, production - in other words, individuality, liberty, property - this is man. And in spite of the cunning of artful political leaders, these three gifts from God precede all human legislation, and are superior to it. Life, liberty, and property do not exist because men have made laws. On the contrary, it was the fact that life, liberty, and property existed beforehand that caused men to make laws in the first place. - Frederic Bastiat, The Law
