This does not make sense. One does not have "control" over one's biometrics. The systems that maintain these correspondences belong to other people.

Also, people may want to be identifiable, and/or they may want _not_ to be identifiable. Abstract wealth---having possessions tied to ones identity---would seem to skew the balance more towards the former. Homeless people may be more likely to want the latter. The problem being pointed out here is that this system makes the latter more difficult.
