If corporations are, indeed, people they should be accorded the rights and privileges of people. For instance, corporations might get to vote or get a drivers license.
But they should also suffer the various ills which befall organic people. For instance, people die in accidents or develop horrible diseases or get murdered or mugged. People commit crimes and go to jail or get executed - and sometimes even innocent people have that happen to them.
My proposal to extend full "personhood" to corporations is that, chosen by some random process and accurately reflecting what happens to organic persons, each year some percentage of corporate "persons" are declared to have been involved in accidents or were the victims of violent crimes. And are instantly and without warning terminated - disincorporated - killed off as it were.
Some other percentage are deemed to have developed a disease and are rendered capable of only limited activity for a time with most of those inflicted recovering but with the balance dying.
Some die at birth, some die in infancy, some live to ripe old ages. But they all die. And they die in ages as do organic persons - some statistical percentage die at different ages according to actuarial tables. And so should corporations. The oldest real person is maybe 115 years old so no corporation should be older.
Corporations which break laws should be prosecuted and, if convicted, suffer the same fate as would an organic person. Probation, jail time, or even execution. With some percentage of those being unjustly convicted and innocent of wrongdoing but suffering the punishments anyway.
We might even consider tax laws - why should a corporation get special tax laws? Make them do their taxes using form 1040 and the standard tax tables. And no multi-nationals. Do organic persons get to declare citizenship and residence simultaneously in multiple countries?
Or basic laws against slavery? If a corporation is a person, no corporate person should be allowed to own another corporate person. No wholly or partially owned subsidiaries allowed.
We need to do so much more to bring the rights of true organic personhood to corporate persons.
