> Unless you consider x-rays and other similar imaging systems to create “naked” images.
These are used in medical scenarios with your fully-informed consent. TSA was absolutely not forthcoming about the capabilities of their checkpoint scanners, and they earned the moniker "pornoscanner" for a very good reason.
Additionally, even ignoring the fact that most medical x-rays are used to look inside of you rather than at your skin (why would one use a fancy machine for a surface inspection when the Mk. 1 eyeball is Right There?), the context is completely different in a way that's very, very important.
A pat down is invasive, but the pat down is ephemeral by its own nature.
Just wait until the TSA announces they trained an AI model on sorted naked images.
