All legislation aimed around allowing people to be identified by numbers has been killed due to the whole "mark of the beast" .. "can't buy sell or trade without your number" revelations rhetoric.
As religion has less of an impact on people's daily lives, I expect this to change, but in the past it's been the one thing that's always prevented proper identity management in the USA.
I am curious to know though, if there are other countries that don't identify their citizens with a public id number?
