Public policies are the outputs of government.
Policies made by private companies cannot result in the loss of freedom because only government can legitimately use coercion in order to gain compliance. Coercion involves the use of force by government to gain compliance with policies. A credit card company, on the other hand, cannot legitimately use coercion to collect credit card debts. A private company cannot legally restrict your freedom in order to collect debts. The United States Constitution of 1787 established the constitutional requirements for policy making.
