Anarcho-capitalists have been around for a long time.
Not relative to anarchism. "Anarcho-capitalism" is a very recent recuperation/oxymoron of an ideology that has been anti-capitalist from inception. They'll try to recuperate people from the 1800s or whatever but that's just more nonsense.
Not just techno fascists. There's a lot of these people who watched way too much Mad Max and think that when society collapses, they'll get to be Immortan Joe. They fantasize about being warlords with their own little fiefdom.
