The difficuly here, cougar, is that the definition of "public use" has just been modified from what the past two centuries of law has found acceptable. This decision changes the practice of using eminent domain to create public use facilities (railroads, highways, reservoirs, etc.) to private business concerns that happen to benefit society by creating more tax revenue. (Even that benefit is debatable.) The problem with that judicial paradigm shift is that it gives private business direct access to the powers of government. I am a firm proponent of capitalism. I have rather less trust for government power, but it is useful in its place. When you combine the two, however, you have an extemely efficient engine for corruption.
As to the government taking land against the will of the owners, Black Hawk, Tecumseh, Pontiac and a whole lot of other people are laughing, rather bitterly, in their graves. But that's another thread.
