Libertarians believe that at minimum, the state must protect its citizens and allow them to protect themselves. This involves both a police force and a judiciary for the adjucation of contract disputes.

Not all libertarians. The most famous libertarian, Rothbard, advocated anarchy as most consistent with the bedrock principle of libertarianism: non-initiation of force or fraud.

I'm more a Nozick style libertarian than a Rothbardian. You are correct about Rothbard, but I believe that his recipe for "competing adjudication agencies" is simply a recipe for disaster.

I believe that a single judiciary is necessary, it should just have the absolute minimum amount of power necessary to do its job, and no power to create new laws or positive rights.
