You are dishonest. This was not about crime.
No... this was about coercion. It was about tyranny. And you can have that from the private sector too. What defines a criminal anyway? The government does.
Gangs, etc. practice coercion and the government is there as a force to fight it. But even beyond that, virtually any group in power can limit the freedom of others. It is just how things work. A business that threatens a worker with dismissal if they don't follow rules x,y, and z is a form of limiting liberty, especially if the labor market for that particular individual is limited to none. And as a pro-liberty advocate there is nothing wrong in accepting that because it is true- to deny it is to reject reality; it is to remain an ideologue.
To take that further, heavily unbalanced market power can lead to a lot of power on one side vs. very little on the other. Everything doesn't always have to be black and white- a dark shade of grey vs. a virtual white can be pretty bad too. At the end of the day, you will always have some coercion and unbalanced power- it is about forming a system that limits that and there government has a role (and you seem to agree since again and for the millionth time you support government too when it comes to protecting vs. murders, etc. and ironically you reasoning there proves my point in and of itself).
When I look to issues such as these I think of aggregate utility as a measure for creating policy, partly because I think it is easier to measure than liberty and partly because I think the end goal of libertarianism should be utilitarianism anyway.
