Yeah, but in a way, the core story of the Man Who Has Everything is not the marriage and Jon, but about the fact that Superman can't be happy, because he has the responsibility as Superman. But aside Moore himself is not bent on Superman's marriage, because his Superman's story never had that which I mean not Superman story for DC, but for his Miracleman and Supreme. Though I believe the reason why people don't really love marriage is because of the drama. The drama that is provided by making two beautiful women chasing after Superman is infinitely more fun to write and read then when he is married with a kid. The soap opera, the youthfulness of the woman and Clark, and the innocent mind of young adults are brimming in those writings then the marriage. So that's the selling point that most writers don't want to marriage superheroes.
