I've never had to provide citizenship papers for a drivers lisence.
Passport? Well, you're going to a foreign country. Proof of citizenship is required to get a visa.
I've never had to show citizenship papers for 99% of the public services I use: driving on public roads, using police or fire services, using (god forbid) the coast guard in a boating emergency, using public utilities and water services, using public parks. That would be like living in the Soviet Motherland if I had to continually "show my papers".
Why are you and Tom singling out little kids, SF?
