Your post implies that "ideal" is well defined. I disagree. For what it's worth, I vehemently disagree that libertarian freedom is an ideal in theory or would be tolerated by the vast majority of people if applied in practice.

I would assert that most everything that most people actually enjoy in life is directly or indirectly scaffolded by a combination of socialism, capitalism and authoritarianism—and would be made worse by the actual reality of libertarian freedom.
