The Founders probably couldn't comprehend mobile phones and the internet, let alone modern corporations being granted personhood.
Keep in mind that the founders were some of the smartest, most educated and most powerful people on the fucking planet at the time - Franklin even contributed to our understanding of electricity - so I think that view is not only mistaken but beside the point. They had no need to debate the particular sophistry of our circumstances. The corrupting nature of power was clear to them and we should be thankful that for that.
