I don't want to contribute to the off-topic discussion, so I'll conclude this topic with a clarification. Just as I believe that money should be separate from the state, the monopoly of violence should also be abolished. If we leave the monopoly of violence in the hands of the state, we will not have moved towards a libertarian society; instead, it would be more like a minarchist society that would eventually grow back into a large state. If we believe that the state is illegitimate, we should not grant it any power, at least not voluntarily, and that includes the monopoly of violence (weapons).

Once again, this is just my perspective, and I may be mistaken.
