He wants the government to be run by an oligarchical boardroom that appoints a CEO (literally the term he uses) who tries to maximize the rate at which capital accelerates its own growth. Whatever you want to call that, that's what he is. He technically does support Marxist experiments still, but he doesn't want them to take over the world and prevent capital from developing a cybernetic body that can escape human whims. I'm not the person you're replying to, but I don't really think this is too far off from fascism. It's basically Curtis Yarvin's plan but with ambitions of post-humanism instead of libertarianism. The "meth" answer has a modicum of truth to it, by his own admission he went partially insane after a year-long meth binge, but IMO this isn't really the cause so much as a symptom of his madness. The thing about Fisher's suicide is a non-sequitor, happened way after Land went post-Marxist.
