Where does the Constitution require the SCOTUS to rule based on "intent?" Answer: It doesn't. And anyway, your opinion means diddly. The SCOTUS gets the last word, and they've spoken. CSA is constitutional. Pass an amendment if you don't like it.
See "prohibition."

Feds credibility on this issue is below zero.
It was the intent of the Founders, in their own words, that the Constitution be interpreted per their writings, as it was written. And so it was until the beginnings of the last century, with T. Roosevelt, W. Wilson and F.D. Roosevelt, the great socialists. So you’re saying that you agree with THEM? What would that make you, then? Surely not Conservative!
Pass an amendment if you don't like the original intent of the Commerce Clause. The People have the last word, not the USSC, and not you.
