>The whole premise of antitrust is that monopolies are harmful in lots of systemic ways. We must assume that most are unknown. This is completely untrue. There's a clear economic reason for why a monopoly, defined a certain way, is bad (reduces overall utility, worst outcomes for consumers, and everyone's a consumer). That's why we have antitrust. If the definition of a monopoly is changed arbitrarily, then the original arguments about why it's bad don't necessarily apply, so the concept becomes meaningless. Making arbitrary, unprincipled decisions based on what people not educated in economics feel might be bad is a great way to drive an economy into the ground.
