First, go read
Nozick. Second, forget it, because it's all just hand-waving to hide greed, and no one of the face of the earth you'll ever meet uses it as a guiding principle, the intellectual DC/Reason crowd included.
A bit of notes to save you some time:
1. Every self-claimed libertarian you meet will claim no commonality with the Libertarian Party (cranks), actually elected DC types like Rand Paul or Ron Paul who claim to be libertarians (cranks or actually secret Republicans), or any famousy libertarians online when they get caught saying something dumb.
2. They will claim they don't agree with any of the extreme positions you've laid out, even though they're logical implied by the philosophical premises. A variety of bad logical arguments are presented why, but come down to "well I benefit from that so it can't be that bad."
3. They will claim they're not just rich non-religious Republicans even though they consistently vote that way.
