That's an interesting take. So because I didn't sign the constitution of my state it is null with respect to me?
That is correct.
The justification our Revolutionary Fathers found in breaking away from the British Empire was that the Englishmen of the American colonies had formed a social compact with the government of Great Britain. When Great Britain abused it's power against the rights and liberties of the Englishmen of the American colonies, the Revolutionary Fathers had a casus belli for independence.
Thus, according to laws of natural rights, all people engage in a social compact with their government. In such a compact, people hand over a number of their rights and liberties to the government and in return the government provides any number of services to it's people, especially as a means to protect the rights and liberties their people still maintain.
For example, without government, if a person is wronged he may use deadly force on his own in recompense for that wrong. Under a system of government, people hand over that ability to use deadly force as recompense to the government so that the government may institute a system of courts to ensure fairness when someone is wronged.
However, the most radical thinkers who believe in a system of social compact believe that such a compact must be rewritten every so often. After all, how can one generation of people write a social compact and expect their children, grandchildren, and great-grandchildren to abide by it. That's like saying that I sign a contract to work for a company, but that my son and grandson must also abide by too.
Thomas Jefferson believed in this so much that he suggested that we have a new Constitution written every 19 years. He chose the number 19 years, essentially every time a new generation came about.
But what this also means is that our federal Constitution is something of an illegitimate social compact as well. After all, women, African-American slaves, and Native Americans had no say at all in it's writing even though the U.S. government demanded that such people abide by it's laws.
