Well, we will just have to disagree. Do you seriously believe the people of Virginia took the time to write such a document if they thought it wouldn't be taken seriously. They were ratifying the Constitution with conditions.
I can't speak for them, but if they believed that they could legally resume powers granted to the government any time that they wanted then they were wrong. The Constitution doesn't allow for that, and they accepted the Constitution as passed by the convention. That part's in their ratification document, too.
