private security is not a real option.
Thanks for your polite approach. We disagree and I'm not sure you understand how a free market, a real one, actually works.
Any kind of "security" or policing that is funded, not by willing customers who freely choose a service as individuals, but instead by captive customers, is already a failure.
How do you first threaten to use force against a person to make sure they pay you, then also declare you are "protecting" them?
If I did that to you, would you accept it ?
Wouldn't you rather be able to hire somebody you choose, rather than somebody that is imposed on you?
