If they are drag-queening as libertarians for some nefarious purpose then they are just Machiavellians.
I've always thought that a smart, resourceful, and persistent person could live as a libertarian in any society from anarchy to totalitarian. In a sense, Stalin lived like a libertarian in the Soviet Union because he could do whatever he wanted.
I would only count a person as a true libertarian if he wanted for others what he wanted for himself. The person "living as a libertarian" rather than being one is someone like McAfee who came into a bunch of money from his software and then went on one heck of a crazy spree, or someone like the Wolf of Wallstreet and his hanger-ons, or the former KGB agents who morphed into Russian oligarchs.
You’re right, they aren’t really libertarians despite their claim to be. I’ve been saying that. Real libertarians are guided by natural law. The others just see it as a means to install fascism and socialism by deliberate misuse of individual freedom to abuse people to show freedom doesn’t work.
To them, libertarianism is a means to fascism. Fascists want strong government because they can get the government to give them their sector of the economy to control in exchange for enforcing government dictums.
As I said, libertarianism only works within a country, but it cannot be made to work as a one world government.
