With all due respect arragantsob, you've got the wires completely crossed as to why the Founding States made the federal Constitution. In fact, Judge Andrew Napolitano will take about 3 minutes to read the federal government's relatively short list of constitutional Article I, Section 8 powers to you.
Judge Napolitano & the Constitution
And the Supreme Court has officially clarified, in terms of the 10th Amendment, that any power that is not in the relatively short list of powers that Judge Napolitano just read to you is prohibited to the federal government.
”From the accepted doctrine that the United States is a government of delegated powers, it follows that those not expressly granted, or reasonably to be implied from such as are conferred, are reserved to the states, or to the people. To forestall any suggestion to the contrary, the Tenth Amendment was adopted. The same proposition, otherwise stated, is that powers not granted are prohibited [emphasis added].” —United States v. Butler, 1936.
The reason the Constitutional Convention was called was to increase the powers of the Central Government and decrease the powers of the States. And those powers were given to the federal government. This is why States’ Righters like George Clinton tried to sabotage the CC. But the Constitution did just that - Article I, Section 10 removed most of the states’ powers to cause harm to the nation. The use of the phrase “explicitly confined to...” wrt federal powers was voted down. Even specifying certain powers does not limit the means of carrying those powers out. Hamilton’s essay on the constitutionality of the National Bank is the definitive description of constitutionality. He was the greatest lawyer of his day and the most familiar with and understanding of the Constitution, writing 2/3s of the Federalist.
