I think you have a deep misunderstanding of libertarianism (which is your right of course). Libertarians don't necessarily not believe in laws, they simply don't believe in a monopoly of laws and law enforcers. This is kind of the whole point. Its clear that in your world view "justice" is somehow inexorably tied to government, but there others that disagree (which leads to your confusion in thinking that because someone asks for justice he is necessarily asking for government).
To illustrate this a bit better, perhaps using an example that you probably agree with Libertarians on: just because libertarians believe drugs should not be illegal, does not necessarily mean they believe drug use shouldn't be discouraged or treated. It is not hypocritical to fight for drug decriminalization but then seek rehabilitation programs for your drug addicted friends. That is in no way acquiescing to the need for drug control -- it is using a different tactic to fight a problem both sides may very well agree exists.
Similarly, it is not hypocritical to want the government to stay out of currencies, but still want a method of punishing thieves. You may believe other methods don't work (just like there are a lot of red voters who think its naive to think not putting drug users in jails works), but that doesn't make the other position inconsistent.
