The point is the OS manages your fingerprint, and even if you have it, you can't easily send a stolen fingerprint to the OS.
If you have access to the hardware, that's a whole different attack vector.
For example, how do you handle compromise (I suspect fingerprint mills / printers are not ubiquitous just because there is no demand for fake fingerprints; technologically they should be easy to make). Also, do you really want a unique match every time you log in from different devices (e.g., work and home); etc., etc.
Sorry, fingerprint solution may be worse than the disease it is trying to cure.
