If corporations were people, they would be subject to things like the 3 strikes law and the death penalty. People don't get the chance to simply pay fines for harming people.
It would be inconsistent to say: If you do something in the employment of a corporation you have same duties as anyone who acts on his own, but none of the rights.
Otherwise they are wanting the rights of a person with none of the obligations and thus should not have them.
If the entities are exchangeable (as you treat them) then the premise void. Are you sure you understand the problem? Exchanging one for the other may work in semantics but not in physical reality, because only one of them is physically real.
P.S. Sorry, if my previous comment wasn't clear. It was for me, so I assumed it is for others - it happens with me.
