I guess we could dig deeper and ask "what is the purpose of gaining wealth?" and "what is the purpose of money?". One answer to the first is that wealth can be used to change the world. Small scale wealth can change things for you alone, like buying a nicer house. Large scale wealth can change things for everyone around you, like supporting a political platform of your liking. In the same vein, money as a means of transaction is supposed to capture the social good that is gained within every transaction and make it abstract so we don't have to specifically barter for what we want in the present. If we accept for the sake of argument the above, then we can examine if corporations are really doing social good, because if they are not then the ought to be restructured. This line of thought is what lead to the anti-trust acts of previous eras, safety regulations, food and drug regulations, and general business regulation in the present day. We have previously acknowledged that businesses can gain wealth, and power, without adding social good and as corporations are an abstraction created by society, it's well within our rights to change them for societies betterment.
