Mostly done by states. Two bomb attacks by the US government killed 185,000 people, including women and children. Nazi Germany killed in the holocaust alone 17,000,000 people. What about the genocide in Bosnia, the state killed over 100,000 people. Oh yeah what about the USSR under Stalin they killed over 10,000,000 people. I could go on and on. Enslaved women and children, mass murders, almost all of these events are carried out by the state. So I think maybe you need to study history to see why it IS NOT good for the state to have a monopoly on violence! Your claim is so absurd as to be hilarious! Sure, people have a desire to use violence to solve disputes. But instead, we should let libertarians resolve disputes, because they respect freedom totally. So, we should have libertarians gain the ability to exert the most violence, because they will use it in the way that is best for humanity and in the way that the least number of innocents will be hurt. Indeed, they will prevent innocents from being hurt by using violence against those who are not innocent! And so you just gave a great example of why Totalibertarians need to come into power, and why we need the Worlds Totalibertarian Liberation Army to become the force with the most ability to use violence in the world. The states monopoly on violence has led to over a hundred million deaths just in modern times. You sound like a total fool to advocate that the state must maintain a monopoly on violence for the good of the community. Uhm, no, Totalibertarians must gain a monopoly on violence for the good of the world! Totalibertarians say people can duel if they both consent to it, and do not put others in harms way. There is nothing wrong with two people agreeing to fight to the death. Even the bloods and the crips can have all out gang warfare, so long as they all consent to it and do it in such a way that there is no risk of others being hurt. Sure sure, we NEED libertarians to have the ability to use force. Libertarians need to be the most powerful group in the world, so that we can keep everybody else in check to prevent them from violating the rights of others. Sure negotiation is preferable, but if people can not agree to do this, we need libertarians to step in and enforce libertarianism. Police use extreme degrees of violence against innocent people. A cop who beats someone up and puts him in prison for using drugs, should be shot through the head. A cop who arrests someone for using drugs should himself be shot through the head. He is a kidnapper, an armed robber, a terrorist. We need to exterminate people like this, or at least go to war with them until we take them completely out of power. Even after they are out of power we need to try all of them for war crimes, and many will likely be hung or executed by firing squad. There should not be a free market in violence. There should be a Totalibertarian dictatorship that keeps a perfect monopoly on violence. Other agencies can act in our name, but if they stray from Totalibertarianism then we will use violence against them as well. In some ways it was freer. But I do not say we should go back to the past, I say we should go to the future, and the future must be Totalibertarian.
