I posed the question to a state department regarding my birth cert and why I need to use it when applying for Government documents i.e. Passport, Driving License... They replied saying it was to prove citizenship, not to ID me, as ID is a result of the production of the BC in the first place. Now, I'd imagine they require it to notify the proper departments that we are applying to benefit from our security and are creating the presumption that we accept surety for the PERSON in relation to whatever ACT/STATUTE provided for the requested documents... :p
