It's not clear to me. Care to elaborate? Seems like a good thing to know how many citizens are in the country, for keeping track of voters if nothing else. In Denmark we have a government sponsored two-factor authentication system linked to the Central Person Register or CPR number which every citizen gets assigned at birth. The two factor authentication is used for all communication with state and municipal and for all banking. Works quite nicely from my point of view. Makes a lot of things a lot easier.
