Okay your argument is of course legitimate and it is theoretically possible for things to work out in such a horrible way. However, if these people existed in our society today, I think they’d immediately try to take control of the government and force their will on the rest of society through the state. I don’t think that a government represents a barrier to these people. On the contrary, they would use the government to achieve their ends. It is estimated that hundreds of millions of people were killed by their own governments in the 20th century alone. These governments did not protect their citizens but killed them. Today governments are not protecting the citizens either. They are constantly stealing wealth through taxation and inflation.
