Saying that there is “no legal requirement to show an ID” is truthy but misleading. Federal law gives the TSA authority over “screening” passengers: https://www.law.cornell.edu/uscode/text/49/44901 (“The Administrator of the Transportation Security Administration shall provide for the screening of all passengers and property, including United States mail, cargo, carry-on and checked baggage, and other articles, that will be carried aboard a passenger aircraft operated by an air carrier or foreign air carrier in air transportation or intrastate air transportation.”).

That means the TSA can do whatever it can get away with labeling “screening.” It doesn’t matter that Congress didn’t specifically require showing IDs. That’s just one possible way of doing “screening.” Under the statute, the TSA is not required to do screening any particular way.

From TFA:

> The Paperwork Reduction Act (PRA), which is set law, provides a “complete defense” against any penalty for failing to respond to any collection of information by a Federal agency that hasn’t been approved by the Office of Management and Budget (OMB), isn’t accompanied by a valid PRA notice, or doesn’t display a valid OMB Control Number.

As the article works through, as a Federal Agency the TSA cannot just label stuff "screening" and demand money, or at least, they can't do so and then make you pay it.

> doesn't matter that Congress didn't specifically require...

Actually it does matter. Chevron deference is gone. If Congress didn't specifically approve this method, it's not legal

How can it be legally considered screening if you can pay $45 to bypass it entirely?
