What did it mean to the founders? With states imposing import duties on each other?
No barriers to trade between states, is the original purpose.
Not the nit-picking control of every bottle of olive oil in the entire nation.

If that was the sole purpose of the Commerce Clause then they would have said so. The clause would have said "there shall be no economic or other barriers for trade between the states." Instead it says (paraphrasing): "the congress can regulate trade between the states". Like it or not, that's what it says, and I have no problem with truth in advertising.
