  The global objection rests on very strong claims. Perfectionists can reply that those who advance them exaggerate valid worries about the potential for states to abuse their power. In addition, they can argue that the global objection threatens more than perfectionist politics. If states cannot competently promote the good, then, for the same reasons, they may not be able to enforce justice competently either (Caney 1991). Finally, perfectionists can argue that institutional safeguards, such as legally codified rights, can be effective in preventing the abuse of state power, including state power that promotes perfectionist goods (Sher 1997).
