Nonetheless, Kelo was an outrage. An utterly visible example of turning a similarity into an identity: since giving the properties to a private entity would result in a public benefit (similarity) it was the same as public use (identity). A typical twisting of words by government for government.
Anyone who doubts that court meant to increase government power need only read several SCOTUS decisions to see for himself how sharp these costumed government attorneys are--they can find the subtlest distinctions you care to name. They have no problem seeing differences. Seeing the difference between public benefit and public use was easily within their ability.
