Just to play Devil's advocate here, what gives you the right to travel anonymously? When you fly, you are signing a contract of carriage that contains all kinds of restrictions and provisions. Reporting to the government is simply one more.

And nobody says you have to fly. You could choose a private car, train, bus or boat. Passenger airliners have been proven to be weapons of mass destruction, so why not track every person who uses them?
