  The reason for saying that the state establishes justice is that, in Joseph Raz's words, justice and morality more generally, underdetermine the legislation necessary to bring about justice in a community. This means that one can implement the same principles of justice by means of many different sets of rules. But one can treat others justly only if one is on the same page as the others. So what is just in a particular circumstance will depend in part on the set of rules that the others are acting on. To the extent that the state determines the basic framework of rules, it determines which actions are just and which are not. One does not act justly, on this account, by deciding not to comply with the state one lives in and sending money to another state or association. If one fails to comply with the rules of property or the rules of exchange, one treats others unjustly. The options argument suggests that somehow there is a way that one can discharge one's duty to others by doing something other than obeying the law. Instead of obeying the law of property of the society in which I live, I may simply decide to send money to another part of the world where property rights are enforced. But this argument fails to appreciate the central importance of law to defining justice among persons. Though not all laws are just, justice among persons in any even moderately complex society requires law and obedience to law.
