[Tangurena2]

Because it feeds into the "mark of the beast" thing. State legislators want to appeal to the fundamentalist crowd so they occasionally have to make noises to satisfy them. Since enough people in my state believe such a thing about Social Security numbers, there is a form that the DMV (who I used to work for) has for people who are against SSNs due to religious reasons (SSN required for driving & occupational licenses by Uniform Interstate Family Support Act [0]).

> It also forced all people, great and small, rich and poor, free and slave, to receive a mark on their right hands or on their foreheads, so that they could not buy or sell unless they had the mark, which is the name of the beast or the number of its name. [1]
