The point is, like you mentioned, the constitution enumerates the Power of the federal government, not JUST the limitations on the said government! This means, if it's NOT in the constitution, then the government does NOT have that power, and I DO. The constitution says nothing about regulation of drugs, mass surveillance, or privacy. This means I HAVE those rights and the government has NO right to infringe my rights. Pretty soon I'll have to consult with a "licensed professional" to take a shit, and the NSA will have a camera at the bottom of my toilet, thus completing their constitutionally prescribed mission of crawling up the ass of every American, to make sure that no terrorists hide there, of course.
