This is the rebuttal I gave him in the thread, if anyone's interested.
Corporations aren't relationships. Michael, stop using legal terms you don't understand. For one thing, partnerships, LLCs, PCs, PLLCs, sole proprietorships, and others ARE corporations.
A corporation is not a marriage. It's not even LIKE a marriage. A corporation is a legal entity unto itself, completely separate from the people who created it. A marriage, however, is a contract between individuals. While married people file taxes jointly, a corporation is taxed by itself, and its shareholders file their own personal taxes.
Corporations own property, marriages do not. (Married people own it jointly.) If Bonnie dumps toxic waste into a river, the government prosecutes HER, not her marriage. If the Bonnie & Clyde corporation dumps toxic waste into a river, the government goes after the corporation.
Corporations outlive their shareholders; shares can be handed down from one person to another. A marriage ends when one person dies.
Corporations enter contracts, and marriages do not (although the people IN the marriage, jointly or separately, can).
So you don't "organize yourself into" a corporation any more than a carpenter "organizes himself into" a birdhouse. It's not a "relationship" between anyone.
Second, corporations owe duties to more than just the people involved in them. They sell to or service the public, meaning that the government has to monitor the corp's activities in dealing with outsiders, so that there's no malfeasance, and does this conferring incentives and penalties based on how likely a corporation, by its structure, is to commit a certain type. Marriages don't owe anything to anyone; your marriage can't cause harm to someone else, and doesn't need to be supervised by the government.
Lastly, you said yourself that anyone can organize any type of corporation. This is correct, so why shouldn't anyone be able to "organize" a marriage? We don't distinguish PCs from LLCs based on the gender of the people involved, do we?
