I agree with much of the article. I was out of my house at 17, spent seven years in the Marine Corps and had kids and home by 23. Yet, I don't see it's relevance to the conversation.... really.
What I don't understand is this concept of a "libertarian relationship". In order to be a good libertarian does one have to fit into the confines of this so-called "libertarian relationship".
I think were skirting the realms of a cult or religion when we try to use this thing called "libertarianism" to shape each and every factor of our lives.
