The limited liability granted to corporations is an excellent reason why they shouldn't have the same rights as a person. After all, they don't have the same responsibilities.<p>But a more basic reason is that a corporation is not a person! It's not a group of people, either, or they would call it a collective, co-op, or a partnership -- it is its own thing and there is no inherent reason whatsoever why it should have any rights at all, including the right to exist except as explicitly allowed by law.
