A good name for this school of thought is Regime Libertarianism. The modifier identifies the means they choose to bring about their view of what constitutes freedom. It identifies the target audience of their urgings and pleadings. It identifies the institution that they believe to be the first condition in the advance of civilization. It spells out precisely where their ultimate loyalties lie. Thus do all plans for freedom come down to redirecting the attentions of power but not uprooting it altogether.
It's a favorite phrase of Lew Rockwell, who as far as I can tell coined it in this 2005 article.
