THE PIPELINE is of national strategic importance. a vital civil use
thats what emminant domain is supposed to be about not specifically for private gain
Yet the pipeline clearly enriches a private entity. Pipelines receive eminent domain powers from the government precisely because it is seen as having public interest or good. If it's okay to enrich a private entity provided there is public good, then Kelo and every court case like it going back more than a hundred years is utterly vindicated in their conclusions.
If Kelo is wrong, then Keystone is wrong under every circumstance, and the only way to make it "right" would be to nationalize the oil companies or at least the pipelines themselves, perhaps charging TransCanada for their use, or opening them up for use by any other company.
