You can do your own research. I have no obligation to provide it for you but i will do so anyway.
An ANCAP creates a ANARCHOCAPITALIST FAQ and explains private law: http://ozarkia.net/bill/anarchism/faq.html
quote: "Imagine a society with no government. Individuals purchase law enforcement from private firms. Each such firm faces possible conflicts with other firms. Private policemen working for the enforcement agency that I employ may track down the burglar who stole my property only to discover, when they try to arrest him, that he too employs an enforcement agency.

Right, and none of this supports your initial claim, as I have pointed out. Nobody said you have awn obligation, to do anything. Thanks for the comment.
