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.
That's a business.
A corporation is a legal entity that doesn't give a damn if the people drop dead, as long as its papers are filed properly and it has a bank account. That's just a fact.
People do business THROUGH corporations. The corporation is not the business - the corporation is the legal shield the people doing business have elected to pay for the government to create on their behalf, for which they receive personal indemnification, and for which they pay corporate taxes and follow corporate laws.
