Wellman's Response to the "Egalitarian" Objection to the State's Right

Wellman's response to the "egalitarian" objection to the state's right to exclude is that states can fulfill their duties to outsiders without allowing them into their territory. Fine thinks Wellman's response is insufficient because

A) egalitarians are committed to utilitarian principles.
B) Wellman himself is an immigrant.
C) excluding people who wish to pursue interests specific to that state is still potentially harmful.
D) the concept of "exporting justice" is internally contradictory.
