I’ve read Joseph Story’s writings, and early case law. Story’s writings on the subject seem compelling, and I think they’d easily qualify as “scholarly commentary”. Mr. Story himself appears to me to be arguably more qualified to speak authitatively on the subject than any modern scholar.

Justice Story was on the Supreme Court when Gibbons v. Ogden was decided. He voted with the unanimous Court in favor of Gibbons and an expansive view of the commerce clause. Some scholars regard the modern view of the commerce clause as a revival of Gibbons v. Ogden.

If you have a continuing interest in the subject, I recommend that you take a look at the development of the Supreme Court's commerce clause case law from the Civil War onwards. You need not agree with the results, but you would benefit from an understanding of how this area of law developed.
