Playing Devil’s advocate here (no pun intended): there was early controversy about the implementation of the Social Security system that revolved around the assignment of numbers to every citizen. There was a not-insignificant portion of the population which considered that anti-Christian - that it was too “mark of the Beast/Revelations”. A completely superstitious reaction.
Fast forward to today: now that the SS number has become the de facto personal ID for all private transactions and interactions with the government (even though the promise was that it would only be used for the Social Security program), the 1930’s-era fundamentalists may have had a somewhat-valid point (albeit in a “stopped clock” sort of way).
