True, but there isn’t much of a society left. Productive forces don’t really exist beyond artisanal and sustenance production, and neither does organized or capitalist modes of production. There isn’t anything to really organize, let alone lead.

This would be true if they didn't literally come from the NCR - which does in fact have an organized, capitalist mode of production.

The reality is they're simply not Marxists. FotA are closer to Christian missionaries that do charity work.

They live in commune societies where the collective own the means of production, reject money, they attempt to elevate tribal groups through education, they’re anti-fascist and only maintain a tenuous relationship with the liberal NCR, and attempt to recruit through their outreach.

Which makes them closer to utopian socialism rather than full-blown communism.

Society tetters between tribal and early feudal at best, and even then barely. What is a socialist to do in a “society” like that? Volunteer outreach is all that’s left, not like there’s much to do a “revolution” against.

Again this argument would make more sense if the NCR, the Strip, and Caesar's Legion didn't exist. Complex civilizations are coming back and they're reviving exploitative modes of production such as the imperialism of the NCR, the Strip's more basic capitalist model, and the Legion's slave economy.
