There's another important point in here that goes unnoticed... The concept of corporations as "persons" is a concept that came about during the debate many years ago concerning the taxation of corporations by government. Businesses argued that corporations were simply legal entities- not actually citizens subject to income tax. In response, the court created a definition of corporations as persons that has stood to this day. I don't think that those who argue against the "personhood" of corporations have thought all the through the implications of their position. If businesses were to again be considered merely legal entities, they would no longer be subject to income tax.
