Storing the biometric data securely in the digital enclave only covers half the problem. The other half is in the form of falsifying said biometrics to gain access to a device, or physically forcing the actual person to unlock it against their will. With keys that are only stored in my mind, I have the ability to consciously decide that access should or should not be granted.

Studies have shown that amongst human subjects there's a really strong correlation between an economic agent having a gun pointed by someone else at their heads and conciously making choices that posit a positive utility increase for the ones holding the gun.

Maybe so, but it's still their choice in that instance. Some data is with dying to protect.
