Imagine someone reading a first-person account of a drug's side effects on what looks like a patient advocacy page, only to learn an AI generated it for the manufacturer. Under current fraud law, proving deception is slow and difficult. A labeling requirement changes that: omission itself becomes the violation. That's a real, enforceable hook for harm prevention, not just a symbolic tag.
And yes, bad actors may skip the label, but they also skip tax stamps. The point is that the most dangerous content is realistic impersonation, and that line is already legally familiar. We don't need to regulate spellcheck; we need to regulate deception.
