Sorry for devil's advocate here because I agree with you but hypothetically the answer would be verification. ie., Google already has your password, so why would they need to ask you for it when you log in?
Clear Blue is like this, but they use your iris scan. You have to scan every time to skip the line. But the TSA precheck just fingerprints you once when you sign up IIRC
A lot of people have just accepted surviellance for convienience.
People close to me get TSA precheck even though it requires fingerprinting, because "the government already has your fingerprints"
But if they did, why would they need to ask your for them?

TSA sounds nightmarish to me
