Columbia has apparently purchased the overwhelming majority of the land needed for this project on the private market. They didn't simply decide to "lawyer up and kick people out of their land" (also, for what it's worth, the "land" in question was a largely abandoned warehouse district).

The appeal to personal feelings is also misguided. How would I feel if the State of Illinois decided that a new light rail project should run right through my house? Very, very bad! Burn the witches! But that's a textbook case of eminent domain, not an abuse; the only way to argue against it is to enter into a very unproductive argument about whether all eminent domain claims are abusive.

I disagree with Columbia in this case; the doctrine that says eminent domain comes into play simply because the benificiary can make the property more productive is unsettling. But it's still incumbent on us to make valid arguments.
