That's nothing more than the definition of originalism, and makes it no more important than any other historical context. You can read the same sentiments in Bork's books. I don't disagree with them, but this isn't a precedent, just Story's opinion [not even obiter dicta, since it isn't part of any legal finding.] It's not part of the case law, and it's certainly not part of the instrument.
The quote from Martin is laughable. It's nothing more than an historical note -- which, by the way -- Story also used in supporting his claim for jurisdiction.
So, is the historical context also part of the Constitution? By your "argument" it would appear so. Luckily, Story didn't rely on originalist arguments entirely to establish his point, but actually cited chapter and verse where in the Constitution the Supreme court was granted such authority by The People via the Convention and the States who ratified it.
Two strikes. I'll give you one more swing, and then you're out.
For something that isn't part of the instrument the preamble certainly got quoted a lot, both in case law and in studies of the Constitution itself.
