Now, I have Global Entry (which includes TSA Pre).
I rationalized it in a few ways:
* "The Government" already has all the information GE wants. Finger prints, photo ID, "interview" (answering the question "Are you a terrorist?"). They got nearly all of this when I got a driver's license. (https://www.caranddriver.com/features/a32035408/dmv-selling-...)
* With modern corporate surveillance, corps already have a shit ton of "my data" that they will happily sell to anyone, including "The Government". (https://media.ccc.de/v/38c3-databroker-files-wie-uns-apps-un...)
* If I'm flying anyway, the airlines already collect (and are legally required to collect) all sorts of personal data that I would rather them not have. (https://en.wikipedia.org/wiki/Passenger_name_record)
