I am not a libertarian, though I don't think all their ideas are bad. I agree it doesn't look like a policy they would support, but I think they get there using the following axioms. 1) It's better for me if there is a functioning common society 2) People will do anything to survive 3) People without sufficient resources will gain them however they can, often inefficiently 4) I eventually pay for externalities These assumptions lead to the conclusion that it's in their interests to have an efficient system to fulfill the basic needs of everyone. There's some grim logic that say that killing people would be cheaper, but most people are repulsed by it and it's often not true in practice.
