I assume you mean "gang" in the sense of, "Hey honey, a non-rivalrous gang converted this luxury hotel into a mutual aid hospital, let's go get that rash looked at."

If not, your assertion is at odds with what Orwell described in Homage to Catalonia.

I'm not even a fan of anarchism, but I am a fan of reading about these things.
