"and which does not extend to or affect other States."

So they're saying that Congress may not regulate commerce that does not extend to or affect other states. I agree. This means, therefore, that Congress may regulate commerce that extends to OR AFFECTS other states.

Thank you for making my "substantial effects" case for me.

You don't stop at affecting other States. The standard you set is that it affects Congress's ability to enforce whatever regulations they pass. "Affecting other States" is a dodge.
