May I also add, in addition to the excellent rebuttals that other commenters have made to you, that you're making a false analogy between welfare and contract law by confusing positive and negative rights. Positive rights entitle people to something, while negative rights protect people from something. The ideals that most libertarian philosophies are based on maximize negative rights and minimize positive rights. This is based on the core insight that one person's positive rights can only ever come at the expense of another's negative rights. Also, strawman allusions to Somalia don't help this discourse.
