How is it incorrect? The Founders enumerated and transferred to the federal government an explicit, limited set of powers. The existence of any particular state laws did not constitute an implicit grant and transfer of power.

Oh, Federal government. I stand corrected on that point.

One thing to consider is that the Founder's idea of power to the states has been long extinct. In the absence of state power, they might very well advocate federal laws against such things. But, that's merely speculation and we'll never know.
