I’ve always heard that abolishing corporate personhood would make them untaxable. I don’t know for sure, but I imagine you’d have to be very careful with that one. That said, I understand the general goal, and I’m for it.

Edit: That was a lazy comment. Wikipedia:

Treating juridical persons as having legal rights allows corporations to sue and to be sued, provides a single entity for easier taxation and regulation, simplifies complex transactions that would otherwise involve, in the case of large corporations, thousands of people, and protects the individual rights of the shareholders as well as the right of association.
