he was one of the few because the idea that monopolies were good for consumers is about a 5th grader's level of thinking. in a perfect world where monopolies serve a single, narrow segment, don't overreach into adjacent markets or sociopolitics, and there's no general uncertainty or strife, you might argue they'd be a more efficient than multiple market participants, but we live in a dynamic and ever-changing world where that kind of thinking is laughably simplistic. monopolists can't resist distorting markets for their own benefit.
