Nope. Where does it say that, once ratified, that a state can walk out on a whim?
#. 10 The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people.
I read this to mean exactly what it was intended to mean - A Prohibition against the Federal Government interference in a State's self-determination. And this is what gave the South all it really needed to secede once the State legislatures (i.e. the representatives of the People) voted for it. "Where does it say that, once ratified, that a state can walk out on a whim?" Because each State DID NOT surrender its sovereignty when they ratified the Constitution they were still able to determine the course of their own destiny. All the Constitution was put in place for was as guidelines for what the Federal Government could and could not do.
Look at Madison's statement ""Each State, in ratifying the Constitution, is considered as a sovereign body, independent of all others, and only to be bound by its own voluntary act. In this relation, then, the new Constitution will, if established, be a FEDERAL, and not a NATIONAL constitution." --James Madison, Federalist No. 39
So if the State determined that the Fed had usurped its authority over a period of time, they had the right and duty to form a government that they felt would preserve their inalienable rights in accordance with the following passage from the Declaration of Independence " That whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it, and to institute new Government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their Safety and Happiness." And this key statement " But when a long train of abuses and usurpations, pursuing invariably the same Object evinces a design to reduce them under absolute Despotism, it is their right, it is their duty, to throw off such Government, and to provide new Guards for their future security."
Now I realize that this is not the way you Yankees view it, but you have allowed your understanding to be misconstrued by Lincoln. So you see, the matter of choice was up to each sovereign State as to whether or not it would remain with the Federal Government or not. The Federal Government really had no legal right to force a State to remain in the Union. And if you read the last line of Madison's statement he clearly says In this relation, then, the new Constitution will, if established, be a FEDERAL, and not a NATIONAL constitution." Well the Constitution was established, and it was a Federal, not a national Constitution.
