Corporations are collections of individuals uniting to operate a joint business. If individuals do not have the right to act collectively then there are no rights.
A "paper entity" means absolutely nothing without PEOPLE making things happen. A building full of machines and information does nothing on its own. At the end of each day, the "corporation" walks out the door, one at a time, and exists only insofar as those people come back the next day. If they (under whatever organizational form the group operates) can't say "we're not going to do X pursuant to individual right R" then their rights are violated.
