Which case was that? What were they doing that wasn't an exercise in correcting an injustice among the states, that they expanded the power to encompass?
I also gave you one in 1829 which mentioned the "Dormant Commerce Clause", a direct reference to the states resolving injustice among themselves without Congressional action.
You still can't provide any evidence that the Founders intended the power to RCATSS to be used for the "positive purposes of the General Government" that doesn't require substantial assumptions about facts not in evidence. All you've done is pile a few inferences on top of each other to arrive at a conclusion, and you've had to do it with inferences that no one else finds rational.

He is misstating Gibbons, in which Marshall placed limits on the Commerce Clause:
"State inspection laws, health laws, and laws for regulating the internal commerce of a State, and those which respect turnpike roads, ferries, &c. are not within the power granted to Congress."
