What she means is that sexual competition from robots would force women, that are too selfish and lazy to bring anything else of value to a relationship besides their sexuality, to have to double down on that sexuality in order to maintain their parasitic lifestyle.

Same thing goes for arguments that sexbots would increase violence against women.

What they’re really saying here is that without a population of sexually desperate, young men eager to play the white knight role in an effort to win pussy, that women who are abusive to their male partners are much more likely to get hit because their victims realize that there aren’t so many ‘white knights’ around to jump them.

No mystery at all.
