Far from being a radical repudiating "the currently prevailing ideologies" I would say that he is steeped in the currently ideologies and just advocating their logical end; dictatorship. The Left and Right are both intellectually bankrupt and now just seek power for power's sake, i.e., they stand for nothing. The society is ripe for a dictator and we will get one as soon as another economic or other crisis arises. The Left and the Right secretly are hoping for such a crisis and that their gang happens to be in power when it happens. Writers like Moldbug are a harbinger of the future of the US as we drift toward dictatorship and they existed in Germany before the rise of the Nazis, laying the intellectual ground work.
Fortunately there is real intellectual opposition to this fate in Ayn Rand's philosophy. You should read "Capitalism: The Unknown Ideal" and more importantly her intro on ethics "The Virtue of Selfishness". She identified what is wrong with the Left and the Right and proposes an alternative ethical and political theory to support Capitalism and her writings are crystal clear and to the point.
