Three pillars of her writing would be missing in fluffy erotica or pastoral fantasy, however:

1) Rape
2) Hating women passionately and constantly
3) Rape

Plus, she enjoys having Anita go through (supposedly) difficult things so that her penii may cluster around her and reassure her that she is the most perfect beautiful sexy hot woman in the whole world, the only one who it's really fun to have sex with in existence. Maybe Merry could go the happy fluffy erotica route, but I don't think LKH can give up Anita or the psychological rewards Anita gives her.
