The best the Bitcoin community should strive for in the short-to-mid term is greater adoption by the average person, not by a governmental entity.

The dollar is backed by the full metal jacket of the United States Government.
or by nothing "in short".
Unfortunately, the petrodollar is something. Basically, a synonym for violence.
Just about everybody who suggests that the dollar is toast becomes toasts.
See Saddam Hussein and Dominique Strauss Kahn as examples that immediately come to mind.
