Perhaps the problem of the idealist understanding of the corporate form (on the model of Hegel's philosophy of law -- an idealist rather than rather than a social-science empirical study) is presented when a society exists primarily to preserve the industrial forms, along with the involvement of a healthy preponderance of the population (and the prosperity of this healthy preponderance). This is a different form of social organization, compared to the types of societies that prevailed when basic questions about the form of civilization in the West were answered. At minimum, these questions would need new answers, if the practice of thinking about what we do is to continue to guide life. (Or perhaps be returned after a century or two of pragmatic exile.)
Is the corporate form a modification of the old sovereignty based on the common good? Historically, this goes from the monopolies to the franchises, to the corporate structures that ruled entire colonial states. Perhaps. But the theory of deputed powers by the chartering sovereign appears to have been rejected over the last several decades. "Any lawful purpose" has become a bit of a fig leaf for spontaneously-arising forms of collaboration accomplishing much of the work of the society.
The reason for a Hegelian reading is on the analogy of his explanation of the building of a cloister, in the PR. One explanation could come from an empirical explanation, that a certain society needed a place of repose; another comes from the ideas, that there is something in the human spirit which seeks this form of existence. Over the last two centuries industries have transformed the planet, multiplied the population, and solved many problems. The philosophers in the West adopted a pragmatic approach, suggesting that the event would reveal the truth, and largely, this allowed industrial forms to flourish. (The East had a more sociologically-inflected form of industrialization.)
But now, having accomplished much at great cost, both human and environmental, perhaps it's time to explain what it was that arose in humans during this time. If only not to worship the work of our hands.
Perhaps.
