Government has a monopoly on the claim to legitimate use of force. All elements of this statement are crucial. The Libertarian objection neglects to consider "claim", "legitimate", and most aspects of "monopoly".
I do agree and understand that, and I'm not a libertarian. My main issue here is that big governments has the same issues than big companies. We must break then all, not only big companies. My provocation was about that, not the use of force per si, so I may use the wrong words in the previous post.
