I suggest reading Chaos Theory by Robert Murphy or at least this chapter of David Friedman's book, The Machinery of Freedom so we are on the same page. Government services aren't magically immune to economic laws, and instead magnify the failings inherent in trying to disregard them. Security and adjudication are not fundamentally different from other services.

Government doesn't "allow individuals to freely exercise their rights," instead infringing upon those rights as a necessary and fundamental aspectbofnits operatuon, and this does not provide "rationale or reason for such an authority." Governments are various gangs warring against one another and against us.
