> Companies are supposed to do everything they can to beat their competition. That is simply called "being competitive."
Real competition is stabbing your competitors in the face and taking their stuff. We prohibit that because it rewards the wrong kinds of competitors. Prohibitions on anticompetitive conduct are rooted in the same principle.
Under laissez-faire (i.e. rights-respecting) capitalism, the initiation of force is barred. Prohibitions on "anticompetitive conduct" are separate from that. They are a restriction on what companies can do in addition to not using force.
