Dr. Draugnar, Esq., that's more or less the definition of a circular argument.
Also, this thing is much more complicated than you seem to think. Even assuming everything the NSA has been up to is covered under the Patriot Act (I don't know since I haven't read it; have you?), it still could have done PLENTY of other illegal things and could have broken other laws. Your if A then B then C analysis is a gross oversimplification even if it's broadly right (which, not being familiar with the legal issues in detail, I can't say; you seem to know everything about it, though).
Also, it isn't right to say there's Supreme Court approval thus far. What there really is is the absence of a ruling on the issue. Rather a different thing. In addition, there is a circuit split on whether the agency's actions were constitutional, so it's very much in the air still as to what the final situation is.
In effect, you're saying that since the president did something and Congress hasn't acted to stop him and the Supreme Court itself hasn't weighed in then everything's kosher. That's nonsense.
