Not necessarily. There are indigenous societies from all across the world who were communist for millenia, and many who still strive for it while capitalism is forced upon them. They often are more anarchist in structure.

But even assuming that state power of some degree is required, there is a lot of room for debate about how much. Original commenter seemed concerned about authoritarianism, I assume that their understanding of communism is Stalin's USSR. There are certainly ways to be auth/com without going that far, and that commenter may find those appealing.
