Far right, slight auth. The government should have a well defined boundary of influence and have the ability to do that (and that alone) well. The issue with libertarianism is that it tries to solve a problem caused by the government putting its hand in A by removing the government's hand in B.

Take marriage, for example. If the government didn't offer tax breaks for married couples with the goal of encouraging families to have children, they wouldn't have to define what a marriage in. But libertarians want to take the halfway trip of allowing the government to stick its hand into the tax aspect of marriage and also define marriage as broadly as possible, even if it defeats the original point of the government being involved entirely. Pick one and stick with it, but picking both looks two-faced.
