This option the consumer retains of being able to buy security wherever he pleases brings about a constant emulation among all the producers, each producer striving to maintain or augment his clientele with the attraction of cheapness or of faster, more complete and better justice.If, on the contrary, the consumer is not free to buy security wherever he pleases, you forthwith see open up a large profession dedicated to arbitrariness and bad management. Justice becomes slow and costly, the police vexatious, individual liberty is no longer respected, the price of security is abusively inflated and inequitably apportioned, according to the power and influence of this or that class of consumers. The protectors engage in bitter struggles to wrest customers from one another. In a word, all the abuses inherent in monopoly or in communism crop up.
