you know what it means....
The idea of a limited national power under the Constitution is a joke. There's Article 3, sitting right there, with nothing to stop them.
The point for us is not to question whether or not the national government OUGHT to possess Power X. We must recognize and accept that they DO possess it, using powers granted in the Constitution, with no appeal. Then we must ask the next question: What then?
But most people can't get to that next question---what if the Constitution is fatally flawed?
From George Washington's Farewell Address
" If, in the opinion of the people, the distribution or modification of the constitutional powers be in any particular wrong, let it be corrected by an amendment in the way which the Constitution designates. But let there be no change by usurpation; for though this, in one instance, may be the instrument of good, it is the customary weapon by which free governments are destroyed. The precedent must always greatly overbalance in permanent evil any partial or transient benefit, which the use can at any time yield."
