But consider why someone might consider it public use. Certainly city hall is public use. Certainly the expansion of a highway is public use. What about a park? You know, with benches and trees and grass and such. That's public use, right? What about a zoo? They'll probably charge admission. Is that public use? Well, if that's public use, what about a stadium? The city will own it. They'll have public events there. It should be noted that this is a very big reason why stadiums are not more often privately-owned. It's much harder for the private owner to sieze land. So, for those who lament the proliferation of public arenas, there you go.
There are also ways around eminent domain, of course. Offer money, if there are hold-outs, build around them and make the property worthless.
Build the stadium itself on non-eminent domain land and build the public parking on the seized land. The parking can be wholly independent of stadium events.
There's a romantic notion of saving one's precious home (or art gallery, I guess) against the bulldozer, but most of the time, it's just greed. The problem with New London is that they weren't Machiavellian enough. If you're subtle, you can take all the land without anyone putting up a fight.
Oh, and it should be noted, that without eminent domain, in order to get large tracts of contiguous land (for stuff like stadia, not for a big box store), you have to buy things like farms. So, for anyone who laments the dwindling farmland, it's worth keeping in mind.
Every action has a consequence.
The zoos in my town are private. The ball parks are private. One of them was built on partially stolen land.
Parks should be built on property acquired legally and ethically.
Governments should not be in business. Governments exist to defend the rights of the citizens. Nothing more.
What you call greed is nothing more than your opinion of the motives of rightful property owners. Motives, of course, are irrelevant.
Kelo was an abomination to freedom loving people. The small mischief they have caused so far is just the beginning. Governments have been abusing property owners ala Kelo for a long time, but this time the court gave them the stamp of approval.
The misuse of government power in the story above may or may not be technically a Kelo situation, the story is ambiguous in some ways. The principle however is the same.
Property taken for the benefit of a third party or the government themselves via increased tax revenues is wrong. It is immoral. Your mileage may vary.
