As the foundation, the cornerstone, the most base part of said "Corporate law". Corporations do not exist without some humans behind them. There are no fully-autonomous corporations in corporate law (despite what ethereum would have you believe) . There are only groups of people. Those people, officers of corporations, impart the personhood - The Corporation is just an embodiment of the collective action of the officers.

Well, you don't really need to attribute "personhood" to corporations for that, do you?

You just need to codify into law what rights you afford the runners/owners of a corporation when acting on its behalf, and how blame/consequences/fines etc is transferred to the runners/owners of the corporation when they make shady shit.

In fact you could have more or less the same corporate laws as today, and not mention a concept of "personhood" there at all.
