> If it were enough of a problem that the bad outweighed the good, people wouldn't use it, but yet they still do, so it's not enough of a problem.
The problem is that while this is true, in practice it's more like the mandate of heaven than laissez-faire economics. When political power structures are involved, and thus the status quo itself is reliant on the omnipresence of certain economic forces, there can never be a drawdown under normal market forces. There is an intentional, exerted force which unbalances the equation in favor of the monoliths. "Enough of a problem" ends up becoming violent social upheaval. In effect, you advocate for normalizing the driver to aim our societal bus off the cliff because "somebody hasn't grabbed the steering wheel yet, so it's clearly an acceptable course." Discounting the fact that the co-driver is pointing a machine gun at the back of the bus.
Adam Smith would be absolutely apalled that we let things get this bad. This isn't what he wrote about at all. The free market is about economic coordination, not letting massive entities do whatever they damn well please at the expense of a society's quality. This is neo-mercantilism, the exact kind of thing he was vehemently disgusted with.
