Curious as to why you believe Kelo was correctly decided.
It's about the Tenth Amendment, Federalism, and States' Rights. When the Feds gain the power to enforce a right, they gain the power to violate it, which would result in the watered down protections we see for everyone with no alternative. As the article above said, after Kelo, many States instituted property rights protections against eminent domain superior to the Constitution, while others did not. Natural Law competition will show which is superior (and as you know, I side with protections for private property).
If you read the piece I linked (which I wrote), you'll see what I mean, especially as regards Federal enforcement of individual rights by "Selective Incorporation."
