The essence of representative democracy is that the people elect representatives who are basically as limited as they are. Anything else would feel uncomfortable and be deeply confusing to voters. Hence the utter incompetence of Congress during the Facebook hearings and, frankly, a similar incompetence in every single area of modern life. The problem isn’t the way we regard monopolies; Adam Smith was very clear these were the inevitable outcome of systemic government failure to regulate properly. The problem is that our system of governance is utterly unfit for purpose, unable to cope with the complex inter-connected global world that clever technologies have made possible.
