Some theorists claim that externalities are probably the most legitimate reason for state intervention in human interactions. The ethical case for intervention is that it can presumably increase overall economic efficiency. This article demonstrates that, even if one accepts this ethical principle, the usual choice of externality-generating actions that are believed to justify state intervention is purely arbitrary.

In fact, according to the definition of actions with external effects, any human action in a multi-individual society would qualify for regulation under the banner of improving economic efficiency (i.e., internalizing externalities). However, the nature of human existence renders this internalization impossible. Thus, we end up with a paradoxical situation where every action inevitably fails the ethical criterion we have put in front of ourselves.
