Given that communism is a sci-fi imagining of what the world will look like in the age of post-scarcity, the last point is unquestionably true. We have never achieved post-scarcity. It remains science fiction.

Most imagine post-scarcity will be awesome. While one can never know for sure, for all intents and purposes, the first point is also true. To the best of our knowledge, achieving post-scarcity will be awesome. It is why everyone, even (and in particular!) the USA, is striving to get there someday.

Communism imagines that statehood will come to end, so "countries", in the context of communism, doesn't make sense. It is likely confusing "communism" with "Communist Party".
