I think you're pretty much right and the only reason the upvote ratio doesn't reflect that is that you seem not to understand that capitalism necessitates "the government picking winners, working with tech companies to spy on its citizens, and corporate welfare." You will never have capitalism without those things, and that's why people are pointing out that anarchocapitalism is a nonsense fantasy, because it is. So using that as a point to counter something (and I'm not sure what) in the comment you responded to above makes no sense.

Neoliberalism does like to paint itself as a more "pure" capitalism, so I don't think calling it "diet anarchocapitalism" is wrong, but that's just their branding. There never was or ever will be a non-diet version of capitalism in that sense, where the bourgeoisie and government don't collaborate and reinforce each other. If anything, fascism is the non-diet version. That is to say, you're also correct that neoliberalism does incorporate some fascist elements. Maoo's response to ChrisLicht in this very thread explains that better than I could hope to, so refer to that.
