Hungry people are a growing and incredibly complex problem. Punishing even a single one of Epstein's clients seems much more manageable. And if we're going for impact-to-effort ratio queuing, this is likely a bit more of a gimme than world hunger.
The point is that society can address more than one problem (or more than one aspect of a problem) at once. The reasoning I responded to seemed to be following the tired cliche of dismissing any problem as not worthy of attention because children are still starving.
