What if someone has ten million shares of some busted Internet startup. In reality he's broke but on paper he's a large corporation: what's keeping him from walking out of city hall with half the town's real estate in his pocket?
This may be, potentially, a worse Supreme Court decision than Roe v. Wade. Mother Teresa of Calcutta often argued that if it's legal for a mother to kill her unborn child, "then what is to prevent me from killing you or you from killing me? There is nothing in between." So what is there left, then, when it has been decided that there is nothing between your personal property and someone who wants to take it from you with government's blessing? There is nothing, not even a semblance of respect for individual rights, at all. Together with rulings stating that derivative products of your personal being can be patented, today's ruling makes us little more than serfs at best, resources to be exploited at worst.
Bad karma goin' come from this, to be sure.
