Consentment fraud is a lesser difficulty than stealing someone’s wallet at gunpoint or horribly mutilating people and leaving them in a bathtub. And yet, the consequences of this fraud are fatal, more fatal than extorting their entire life savings from a person. You just take someone who’s currently lonely, not really looked after, perhaps at odds with their parents… and hop, their life is over. Drug addicts, rape victims, lonely adults. So much taxes can be saved.
Easy fraud for doctors, with plenty of incentives to commit it, and the highest consequences for the victim.
