Issodhos, at the bedrock, where I think your system is falsely based is your claim that government should exist only to secure individual rights. On what is that based, other than your assumption? Why not common rights as well?
Going down a different road: if the rights are individual rights, then why do we need (or want) a state to secure them? Let them hire their own security. Worked really well out on the frontier. Well, except when someone else had a competing individual right but we don't need a state to settle those issues.
