I think that's clearly nonsense and not a helpful take (if you lie to your kids, unwittingly or not, that will just erode their trust in you). Of course you can find desperate adult actors, just as you can find desperate investment bankers or desperate software engineers who would rather be doing something else. Do you have any evidence that the number of desperate adult actors is especially significant? I think a better angle is to discuss dignity and how porn affects the consumer's own world-view.
