You missed the point. Of course the Contracts Clause applies to the states and not to the federal government. The point here is that there is no need for Contracts Clause applying to federal government to exist, because the federal government cannot do what the Contracts Clauses forbids the states anyway. Of course, that's the theory. In practice, the federal government can do literally anything it wants as long as it uses magic incantations of "General Welfare" and "Commerce Clause", and as long as the nine guys in SCOTUS accept that, regardless of what the authors of constitution meant for federal government to be able to do.
