I dont see Libertarianism as an all or nothing proposition. Like Conservatism or Liberalism/Progressivism there’s a continuum along which an individual can be located. And placement upon that continuum can occur at multiple points depending on views on specific issues.
Indeed, if you look at the Libertarian continuum youll see the hippie anything goes dope smokers on one side, and the Ayn Randian/John Galtesque types on the other. And they are distinctly different creatures.
The continuum is from right to left.
A conservative is conservative on economics, national defense and social issues, a libertarian accepts the economics and then starts listing how far left he is.
