Non-sense. The government was created upon the ratification of 9 states. There were, it seems, four left, who's "people" didn't create it, as you said.
An Amendment needs the approval of 3/4ths of the states to become part of the Constitution. Are you saying that the 39th or 40th or 41st state to vote on an amendment don't ratify it just because it became part of the Constitution before their vote? Just because the Constitution met the stated requirement before New York and North Carolina and Rhode Island and Virginia voted to ratify it does not mean that they didn't create the United States. They were represented in Congress when the Constitutional Convention was authorized. They were represented in Congress when Congress voted to send the New Constitution to the states. They had a voice in the creation of it.
