I suggest you re-post your comments and question on the “General Discussion” forum. You’re likely to get more discussion there than you will on this forum, which is dedicated to economics.
Having said that, I will venture a few comments. Economic theory demonstrates that the market economy arranges production in the manner that most fully satisfies people’s preferences. For the market economy to be sustained, private property and voluntary contract must be given the sanction of law and people must accept the legitimacy of private property and voluntary contract. Given that people prefer to have legal sanction of private property and contract, it doesn’t seem implausible that the services of adjudicating and executing those legal sanction could be done by private enterprise instead of by a state enterprise. If people don’t prefer to have legal sanction of private property and contract, then injustice will reign regardless of how the adjudication and execution of legal sanctions is organized.
