Sorry, John Stuart Mill Was Not a Libertarian/Anacronism
From Critiques Of Libertarianism
Libertarianism as it exists in the United States is basically a mid-20th century American philosophy, at least in origin. [...] basically none of the big old philosophical names can rightly be associated with this mid-20th century libertarianism.
