People often seem to need their revolt to be wrapped in a cloak of authority. Most civil war and revolutions in western history were often one state authority in conflict with another*. The 2 big revolts in American history both involved regional governments in conflict with the central government. For many Americans civil-disobedience will need to wear a uniform or it'll be blown off as evil commie stuff.
*The big exception seems to be the Communist revolutions of the 20th century, but those made everyone go crazy.
