Are you fucking stupid? They don't have a complete monopoly there is a judicial, legislative, and executive branch closely defining their rights, policies, and procedures, protecting the individual citizen from the very security hegemony you claim exists.

Your "system" is just a capital-infused might-makes-right policy, where the rich pay profiteers to ensure their brand of "justice" and the poor are systemically oppressed. In your model, where the checks and balances are intentionally absent, you create incentive not only for people to simply steal rather than produce, but a method for financing the fucking thing.
