I'm not contending the "wasn't really yours" point. Phones get stolen, misplaced, left behind, etc. with enough frequency that "it's your phone and it registered/triangulated with this position" may be strong circumstantial evidence but still isn't proof. That it was used in a manner requiring your finger (still attached to your body) does.
Don't get me wrong, I'm with you on protecting the accused from compulsion to self-incrimination. Just observing that the fingerprint sensor, coupled with the enormous data being collected on/about the device, isn't helping 5th Amendment rights.
