Thank you for the post.
Wouldn't a better argument against socialism and communism be that the "Earth will never be made into hell..." ?
Actually, I see Utopianism not as trying to create heaven, but rather as trying to recreate Eden. Unfortunately, the people who are trying to do that fail to realise something very important: even God couldn't make Eden compatible with human nature. How can any sane mortal expect to do better in a re-creation?
The Parable of the Prodigal Son makes clear what was missing in Eden 1.0, but unfortunately its lessons are far too often ignored.
