I've heard that technically all the corporate counties and states are subsidiaries of the District of Columbia Inc. and have no jurisdiction beyond DC's borders. But by naming themselves after the states and counties, they fool the Americans into thinking that their jurisdiction is the entire state or county. It's just fraud. Something that gives wight to this theory of fake government is that people are finding incomplete or missing oaths of office for many government officials. This is true, for example in the Biden administration.
