I was thinking of a more strategic blackmail angle.

Switch bodies.

Grab their cell phone. Grab something else.

Head to the bathroom for a couple of minutes of compromising photos.

Use their facial unlock feature to email the photos to a secure account.

Money/valuables is great, but your can get caught with it.

The photos are useful for many applications. They could even be sold.

I'm not sure how you'd get in legal trouble if someone emailed photos of themselves to you.
