to me this is evil

I agree. Still, libertarian theory does not promise utopia. It simply promises a society that is more just than today's. Surely it would be better to take the risk of some maniac getting away with exploiting his local community than having the guarantee that everyone on the world is exploited by his local violent state.

To me the idea that one very big criminal organization is gonna prevent the formation of many small ones and that this is something to be happy about is absurd. Let's aim for no criminal organizations instead.
