Libertarianism (small el) is not an offer. It is not a license or permit made available by a ruling class. The only unavoidable truth of libertarianism is that it is not a thing designed for one person by another or by a group of others. The idea of a “Libertarian” “Party” is an oxymoron. Small-el libertarianism is like tao — the tao that can be explained is not the tao. The libertarianism than can be impressed on others is not libertarianism.
