I am not sure if I get the surveillance state angle here. The airline already have a passenger register, so unless you lie on the registration then the plane will have log of the travel. The airline do not offer a way to fly anonymously.
Two decades ago in my country there was also two form of ID/passports existing at the same time. The old one and the new one which had bio-metric data and a computer chip. The new did create a new privacy issue in that you had to give away bio-metric data which the old one did not have. Is that what we are talking about for real vs unreal id?
That is close. They hold a bit less info because it is for internal US use only. Its also about the required documentation to have one issued. Also, the reason many countries went biometric at the same time 2 decades ago is because the US absolutely insisted.
