  Another line of thought offered to support the claim that egalitarian justice duties apply state by state among the members of each political community united by a state rather than among all inhabitants of a region of the Earth or all of the Earth's inhabitants or among all rational agents anywhere and everywhere appeals not to state coercion but to collective goods. The suggestion is that the members of any tolerably well-functioning political community cooperate together through the state to provide crucial benefits to all—basic goods of physical security, property, and the rule of law. In the absence of these goods one would not have a reasonable opportunity to pursue any plan of life. People's compliance with legal rules and basic norms of cooperation supplies these crucial goods to all, and thus obligations of reciprocity are triggered in all recipients. At this point a luck egalitarian consideration enters the argument. Factors beyond anyone's individual power to control importantly affect her good fortune or bad fortune under the existing scheme of cooperation in her political community; hence what one owes to other fellow cooperators by way of reciprocity takes the form of egalitarian justice requirements along the lines of the difference principle. These egalitarian justice requirements are owed by the members of each distinct political community to each other and not to outsiders (Sangiovanni 2007).
