Well, this really is only one half of the story.

We gave exclusive use of force to the govern-cement.
However, we neglected to keep control over the govern-cement.

Before, when someone insulted your honor, you would challenge them to a duel.

Now we have the police/courts arbitrate disputes.

However, what happened is they went even further, as all bureaucracies do, and started filling the place for all self-defence. Even making self-defence illegal in many situations.

Lastly, until everyone can resolve disputes effectively by talking it out, we will have to defend ourselves. This requires shooting people who endanger our safety. Most people do not want to do this, even if they have every right (like self-defence) on their side.

In the Magnificent Seven the banditos should have road into town and bang, bang, bang... no more banditos. But the common person is afraid. The gladly give up their freedom for protection.
