O.K. let's say a gang of 10 men get together and go around to private businesses and offer protection for a fee and if they do not provide that protection money then they will be kidnapped and locked away. We call that racketeering, but when the state does it through the collection of taxation we call it funding the police force.
Every human being is entitled to full and exclusive rights to their own body and anything produced through the investment of that body into labour, thus no one owes any good or service to anyone in which they do not voluntarily agree to provide or perform and any contract not entered into voluntarily is null and void and that includes the precious social contract of the statists.
