Under the current "living document" doctrine adopted by the court the power of the federal government is limitless, and there really is not need for Section 8 of Article 1 as to them "Necessary and Proper Clause" makes everything congress deems " Necessary and Proper Clause" to be constitution, a moronic interpretation of the Constitution who's entire purpose was to limit federal power.
The current court is set to role back some of that, I hope it does but it is unlikely they will go as far I want them to... Which includes going all the way back and reversing Wickard v. Filburn and every decision that built off that wrong.
