A lot of Ron Paul Republicans went libertarian-ish for a bit under Obama only to embrace authoritarianism again under either literal fascism or Donald Trump populism. The Bordertarian crowd also seems more interested in state so ereignty than individual liberty.
Liberty is necessary, but not sufficient, for a moral society. Puritans and progressives want power to force people to be moral. Libertines want to be free to seek hedonistic pleasure with little regard for their impact on others. It's a tricky situation all around.
