Let me illustrate the skepticism I have toward "opting out"
Security force A: Security force A is peacefull fair, and they only use force when absolutely needed. They require a code of conduct, but it is the most lenient code of conduct among all security forces. When customers of force A have a dispute with non-customers, they generally try to be reasonable.
Security force B: Security force B generally offers basic freedoms to their own customers, but not nearly as much as security force A does. Security force B only cares about customers of Security force B. Security force B is actually quite oppressive to those who are not customers of Security Force B. If you swear at a force B customer, and you are not a force B customer, force B will forcibly capture you, and keep you in a dungeon for an arbitrary period of time. If you are in a dispute with a customer of force B, Force B will almost always side with their won customer. In disputes between 2 Force B customers, Force B applies established and arbitrary laws to settle the dispute.
Now I'm assuming that most of you would want to opt out of security force B, But the security force representing YOU isn't the one that you should be worried about. It's the security forces that do not represent you.
Now, when you opt out of security force B. how does that prevent security force B from imposing it's will upon you.
