We do agree
Almost completely. The Free Market needs to be regulated to prevent the formation of monopolies. (Although monopolies once formed are inherently unsustainable over the long run because of free market forces.) My problem was simply with your wording.
"The Free Market is all you need to keep big monopolistic bureaucracies…"
Since there is no free market in a monopolistic system, a better way to make your point would have been something like:
"An unregulated free market can lead to big monopolistic bureaucracies…"
Maybe it sounds like I'm splitting hairs, but people might think I was a bit off if I said: Gravity is all you need to keep airplanes flying. There's some truth in that but it is not the entire story is it?
Also, keep in mind some monopolies exist BECAUSE of regulation. Think of old Ma Bell. Once the government allowed competition, phone service on every level became orders of magnitude better.
