Statelessness is the end goal of communism, yes. I have met so-called communists that think strongarm authoritarianism is the way to get there, and for some reason believe that those authoritarians would willingly give up their power once they've achieved a position where they could implement said stateless society. This is basically what happened in the USSR and China, and is decidedly not the path Marx himself proposed for achieving it. A stateless communist society in Marxist thought is simply the natural progression after late stage capitalist societies, which is not a step you can simply skip over.

I don't necessarily agree with the idea, but I think it's important to be educated on a wide variety of schools of political thought.
