Government is might makes right, just with a nice name slapped on it. Minerva was minarchist, not anarchist, but for whatever reason they chose not to defend their country by force. Somaliland and the remains of Rojava come to mind as present-day ~minarchist governments that defended their territory by force and ~succeeded. The point being is these kind of changes won't be allowed by election or peacefully. The primaries stop the election process and the militaries stop the peaceful separation process.

America did have a period of relatively small government intervention at the beginning, but that took a war with Britain. It also had some periods of it during the pre-founding (some of 1600s Pennsylvania and Rhode Island while Britain was occupied elsewhere). Pennsylvania (before it was a state) in particular was basically straight up anarchist for I want to say, about 20 years.
