do you agree that the function of the Constitution is to tell the federal government what it is permitted to do and not to tell what the states and the people what they are permitted to do?

Having read Article I, Section 10 as well as Article IV I would have to disagree with your statement.

Well, that tells me about all I need to know.

Well, that tells me about all I need to know.

It tells us a lot about you, as well. Like, maybe you need to read the Constitution to begin with. Article I, Section 10 is full of actions forbidden to the states, either completely or which require Congressional approval. As is Article IV.
