Some of us want to be able to cross the country in an afternoon, and not have to spend days on a slow, uncomfortable train to make the same trip. I don't think that's unreasonable.
Certainly not unreasonable. But it does require you to commission your own transport subject to the rules that that private entity seeks to impose. Public entities which indiscriminately service residents and visitors of a given territory would obviate this requirement. But if you're in the US, good luck convincing taxpayers to agree to pay for that.
> subject to the rules that that private entity seeks to impose.
It's not the private entity taking a 3D face scan, nor are they necessarily wanting for that scan to be taken. It's federal laws and regulations being done by federal agents in spaces controlled by the federal government.
TSA is absolutely a government organization, it's a part of the Department of Homeland Security. It was created by an act of Congress, the Aviation and Transportation Security Act. You might as well argue the IRS or FBI or the US Marshalls aren't a government organization. What about absolutely absurd thing to suggest.
> The Transportation Security Administration (TSA) is an agency of the United States Department of Homeland Security (DHS) that has authority over the security of transportation systems within and connecting to the United States.
