For the last time, the Federalist Papers were written for the express purpose of alleviating the concerns of the citizens of the respective states. To explain to the citizens what they meant when they were writing the document. The original intent of the document was to limit the federal government. Only after the passage of the 14th, and its first misreading in 1925, did the Constitution begin to apply to the states in a meaningful way. Any doubts of this see Barron (1833)

Of course, the original Constitution was an infringement on some of the powers the states had under the Articles of Confederation. So your basic premise doesn't stand up to that basic fact - the states agreed to more limited powers when they ratified the Constitution in the first place.
