This is backwards. The vast majority of concepts outside mathematics are pretty hard to rigorously define. The way we approach the problem of trying to find a sensible definition is by searching for examples and counterexamples and performing induction.
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.
