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.
The problem being that libertarianism places a heavy emphasis on absolute private property, which is a positive right. It's my right to evict you by force from occupying an empty apartment in my building unless you pay me the rent I want.
Now, you can certainly argue coherently in favor of absolute private property (though I would argue back, extensively and in detail, against the absolutism), but to do so, you need to start by admitting that it's a positive right.
