>If you're already being personally targeted by an organization professional enough to follow you around, take a photo of your fingerprint on something you touched, then painstakingly reproduce said fingerprint through highly technical means and then gain physical access to your personal device that uses a fingerprint reader to use said fingerprint, you should be aware of your position and have multi-factor authentication set up for everything anyway.
But the whole point is that it's easier than you describe as people make photos with fingerprints themself accidentally, and technical means to reproduce fingerprints are not highly technical.
