The founders rejected the requirements of the Articles of Confederation when they created the US Constitution.
A most important requirement of the Articles of Confederation was unanimous consent. The government was not allowed to do anything without the approval of *ALL* states.
When they created the US Constitution, they failed to get approval from all the states, and were therefore violating the Articles of Confederation, making them defunct.
They also never added "perpetual" to the "Union" described by the Constitution.
Virginia, New York and Rhode Island stipulated in their ratification statements that they had the right to take back their powers from the Central government if they ever decided the Central government was infringing upon the rights of the people of their states.
All laws and taxes all states followed were in the Constitution, which the South had more than equal representation in authoring and passing.
