He found patronage in the American oligarchy (look up his ties with Peter Thiel, for example) and as a result, his ideas are now directly implemented by the current administration, that is 100% subservient to capital.
To be fair I don't follow at all. Are you saying that it's more likely for the US under Trump to become a Yarvin-style ultracapitalist monarchy than, say, an Orban-style just-about-dictatorship? Despite the fact that the first is one crackpot's weird idea on the internet and the latter is a model with a playbook that's demonstrated to work extremely well in practice? (if your goal is to stay in power as long as you can) It just seems.. well unlikely at least?
I mean it's so weird, one day some Republican says positive shit about Orban and the whole left wing media screams "oh no they're going to pull an Orban" and now suddenly it's "well actually no, we heard Vance has once read a Moldbug rant so actually they're going to install a king-CEO". Next day Trump is a fascist, the day after he's "Putin's asset". It gets a bit ridiculous to be honest. Do we really believe the administration believes in anything at all? I'm not convinced anybody running the US right now has the attention span to read a Yarvin post all the way to the end. It just feels like obsessive fearmongering to me at this point, stack up all the bogeymen you can think of on one big pile and say that the Trump administration is all of them at the same time.
I say this as someone who thinks Trump is the worst thing to happen to the world in quite some time. I worry that all this panic actively hurts the opposition and that anybody who kinda sorta likes Trump is going to be very tired very fast of this kind of reporting.
Fascism is always a big tent movement, that is surprisingly lenient in who it allows inside. Ultraliberalists (Thiel...), Christian traditionalists (Vance...), pro-Russians (Gabbard...), etc. They all find a seat in Trump's administration.
You have to remove this idea from your head that fascism is a focused ideology with a consistent system of ideas. It is anything but. There is no grand Machiavellian plan to build X, Y or Z.
My previous comment attempted to explain why Yarvin's ideas came into the public's eye: because he was sponsored by one of the factions that today occupies a prominent role in Trump's administration. Nothing more.
While fascism is internally inconsistent, it does exhibit some consistent aspects, explicited in the short essay I linked you. Close relations with the capitalist class is one of them, and indeed, this ties together Hitler, Mussolini, Putin, Trump...
So to answer your question: no, I don't think we're likely to get a CEO-king. But we will get a generic authoritarian government, which is where Orban's ended too. Not out of sheer ideology but as a result of every faction's pull towards something like that.
You might want to consume less liberal media, as those are forever clueless about what's happening since they can't reason about the prevalence of capital in Trump's politics. Actual left-wing media has been pretty spot-on in my experience, in predicting the general outline of Trump's policies. Deporting citizens? check. Cutting medicare/medicaid? check. Undoing constitutional checks to power? check.
(I do still feel like all the constant outrage blurs more than it reveals, though, and that this article ("plot against america", seriously?) is a nice example)
