I'm not sure whether this is a legal, moral or philosophical position but in the spirit of no taxation without representation then it seems right that all political lobbying by corporations would have to be ended as well.
“Under the designation of ‘person’ there is no doubt that a private corporation is included.” Pembina Consolidated Silver Min. & Milling Co. v. Pennsylvania, 125 U.S. 181 (1888).
Among others. That corporations are people has never really been substantially in dispute (legal personhood is fairly expressly the central point of the corporate form as an innovation where partnerships already existed), though whether particular references to person, persons, or people in the law are intended to refer to all legal persons or only specifically to natural persons is sometimes in dispute.
The outcome of trying is a tax system that only applies to SME.
