Wait till you find out Nozick was an ethicist, that libertarianism is a position within political philosophy (which in turn is a generalization of ethics.)
I’m a programmer, not a philosopher, so I never actually heard of him, but from his Wikipedia entry I learned that “he rejected the notion of inalienable rights advanced by Locke and most contemporary capitalist-oriented libertarian academics,” and let’s just say it didn’t say anything about him getting fired from his job.
