I never told you that for the first time. We aren't talking about taxation, we're talking about regulating commerce. Specifically we're talking about the federal government regulating the internal commerce of the States.
So you're hoping to find the WOD unconstitutional based on the argument that illegal drugs (1) Constitute commerce and (2) that commerce doesn't cross state lines. If I were going to hang my hat on something to show federal overreach, this would not be it. About 70 years of cases are going to get tossed in front of the Supremes showing that drugs extensively cross national and state borders. Are legal drugs capable of being regulated in your world view, or is it just illegal drugs that can't be regulated? What of smuggling? Are all goods out of the reach of the government to regulate, or is it just illegal drugs? Were the tariffs that were in effect from 1786 illegal or was it just the enforcement of the tariffs that were illegal? Are tariffs legal, but prohibition not? What of 10,000% tariffs? Please clarify.
