Ancaps; What do you think of them?

Just as simple as asked, what do you think of Ancaps? (Anarcho-capitalists)?
The most common definition of an ancap i find is an anti-statist, libertarian,and anti-political philosophy and economic theory that seeks to abolish centralized states in favor of stateless societies with systems of private property enforced by private agencies, the non-aggression principle, free markets and the right-libertarian interpretation of self-ownership, which extends the concept to include control of private property as part of the self. In the absence of statute, anarcho-capitalists hold that society tends to contractually self-regulate and civilize through participation in the free market, which they describe as a voluntary society involving the voluntary exchange of services and goods. In a theoretical anarcho-capitalist society, the system of private property would still exist and be enforced by private defense agencies and/or insurance companies selected by customers which would operate competitively in a market and fulfill the roles of courts and the police.
