I'd fall under the category of libertarian. I use this label as more of a guide than anything concrete. It's not a flag to carry and certainly not what the American right has in mind--- historically, or even in the modern sense of the word.
Libertarian is just a polite word for “left anarchist” (to paraphrase M. Rothbard- someone who even admits there's no such thing as "anarcho"capitalism). It has nothing to do with hypercapitalism or hyperindividualism. Libertarianism in its rhetorical form is about removing any and all forms of hierarchy. Not just all things government, but all things business too: abolishing or tackling all forms of unjust power over individuals or groups. The "Right" just uses the shade of its so-called "voluntaryism", things like "NAP", and fringe capitalism (an umbrella, if you will) to hide from the blazing sun of anarchism while enjoying some of its traditional, rhetorical, comforts.
