In answer to the question of what an ASIC does for security.
it acts as a deterrent. The person behind it has been a through a painful process to prove they are who they say they are and have a reason to be where they are and if someone doesn’t have one it acts as a red flag if they are somewhere they shouldn’t be.
Again I ask the question what do people complaining about it say should be done instead? Or do we just trust everyone in a pilots uniform wearing gold (or pink) bars?
