The danger of lost biometric data is far more, though at the moment it is of minimal use. But things like SS, bank account info, etc can be changed if compromised, your bio data cannot. So 15 years from now when it's used extensively for everything from employment to insurance, you will at best be constantly putting out fires, or at worst have your reputation and finance in constant ruin.

btw why would anyone use biometrics on a garage door?
