People who work in businesses are people, businesses are not.
They are, after all, legally distinct entities. When your talking about corporations it's even moreso since the owners of the business generally do not even WORK there.
The people IN the business, even the owners, have liberties - but there is no sane reason the business should have those same liberties.
It makes perfect sense to let Joe the Plumber put up a blog saying Kellogs Turdflakes gives you curly hair, it's quite another to allow Kellogs to advertise that as a feature on television and defraud potential customers (and ALL advertising that is not 100% scientifically verifiable is fraud in my book).
But it gets kind of hard to prosecute false advertising when you allow the companies that commit this fraud to claim they have a right to freedom of speech.
Journalists should have a right to free speech, there is no reason the paper that employs them needs the same right. Publishing the paper doesn't require that at all - only that everybody who wrote for it has that right.
That way, you can sanely regulate what's on the advertising pages for example without intruding on freedom of the press.
The same goes for all liberties.
Benjamin Franklin said of property rights that they are not a natural right at all, but one constructed by society for the benefit OF society - and should last only as long as that is true. Private ownership of any particular kind in other words, should be revoked if a point is reached where having private ownership of the resource is harming the rest of society. Laws created property, laws can destroy it.
I would be rightfully hesitant about any time that individual property is considered for such a revocation, it's risky and should only be undertaken with extreme diligence - but I would be far less concerned if it affected something only corporations own in the first place. Reducing or removing those rights almost ALWAYS ends up being to the greater benefit of society as a whole.
A good example is patents and copyrights (which, while not actually property are essentially used the same way so the same logic applies) massive REDUCING the duration of copyright now will make the individuals in society MUCH more free and only harm a few corporations - who don't have rights in the first place except for what we choose to give them because WE benefit from them having it.
The ability to mock Disney with my own Mickey Mouse cartoon is a far more important freedom than their ability to cash in on him and be protected from such critiques by copyright.
Human rights belong to humans, and only humans - not to legal entitities that are divorced from the entire human condition. They can potentially live for ever, can potentially amass wealth forever, and thus amass resources far beyond human ability - and so distort all of society. They aren't human because they are not subject to human weaknesses, ergo they should not have the rights we grant humans.
