How is it a crime to lie to a woman and thereby obtain her consent to have her breasts touched?

I don't understand this:

Police in Idaho have arrested a woman who impersonated a plastic surgeon so she could carry out breast exams to random strangers....

The victims said they believed [Kristina] Ross because she used medical vocabulary.

She said Ross even gave them a phone number to an actual plastic surgeon's office in order for them to make follow-up appointments.

Ross is charged with a felony — "practising medicine without a licence." Oh, blech, it's the Daily Mail. Why do I keep reading that lurid trash! The charge is practicing medicine without a license. Oh, what bullshit. She wasn't practicing medicine. She was lying to ladies in a bar.

The Daily Mail also makes a big deal out of the fact that Ross's "gender category" is "male to female."
