To return to this:
Friedman is pessimistic about people, which is part of the reason he espouses liberalism: nobody is able to make the 'correct' decision for everyone else, and people are naturally selfish and will put their own interests over others - hence the state is a dangerous thing, far more dangerous than a corporation as it has the monopoly on force - this is a liberal position.

I don't think this is a radical rewriting of Friedman, unless I read something other than that which David Rundle read when I read Free To Choose and Capitalism as Freedom.
