I totally agree with you, this is why biometrics are this weird open for machines, but solved for humans problems. If you don't trust the scanner then it's useless. Depending on your threat model you can do really fancy stuff like retina scans that detect blood flow and temperature or TouchID for less-sensitive stuff like a screen lock.

If you built a system that's so secure that this is the lengths you have to go to beat it then you would be an overnight billionaire if you brought it to market. Like at this point you've achieved human-level verification. Assuming it was small enough to go in phones it would be revolutionary!
