Sure they would have! The elite of the United States that lead the revolution were all extremely mercantile and many were coming to the colonies to run their own little fiefdoms away from the crown.
One should acknowledge how many of the freedoms locked into the founding ideology of the US is pretty close to what libertarians reach out for. I don't know many libertarians arguing against Citizens United.
That isn't to say that the US can't aim for something different, and that the core of the nation today likely believes many different things.
We can choose our own destiny without trying to ascribe every good idea to what a group of people thought at the founding of the country.
