Not the guy you're talking to, but... if people doing business can hide behind the limited liability said business provides then it's fair to separate private communication from business communication and possibly declare that limited liability doesn't come without loss of privacy to ensure the law is being followed for business communications. It's unfair to use personal privacy rights to try and hide illegal business activity thus absolving any actual person from being responsible while also allowing them the limited liability of a corporation so if any wrongdoing becomes known no one can be blamed.
