Not all interventions are good, but that doesn't mean there are no good interventions.
I guess there's a net win now that I think about it. I could have protected with a club. good for me, good for you because I didn't club you in the head.
instead of protecting it yourself, you delegated the job to the government.
libertarians will argue "why not delegate to a private company?"
because we all learned from past experience. it is better for one entity to have a monopoly on violence than multiple small organizations.
Yes, that's how it actually works. You have rights to some piece of land, I have rights to another, we don't step on each other's toes, and if we don't like the split, there are blood-free procedures to resolve disputes. More importantly, neither of us has to invest in clubs and constant vigilance, because we've outsourced that job. So we all save time, resources and effort.
It's not perfect, but it's a useful tool in our toolbox for building societies.
