A totally free market is of course utopia, but a lot of markets actually come close. Think your local butchers, bakeries and mechanics. All business with less than 10 employees and the boss is actually working. There are not that much markets that are actually problematic, but of course we talk about them a lot. Most local markets are actually fine, it's the big multinational corporations that are the problem.

> As for capitalism - capture of the state by monied interests has always been a central feature.

Capitalism is about the concept of private ownership and an economy primarily controlled by the decisions of private business oriented societies. Capture of the state isn't necessary, but common and normal up to a point.
