In Kelo, we are seeing the Great Debate between Justice Scalia (joined by Justice Thomas) and Justice Stevens over how the Court should read the Constitution. Does public use mean use by the public? Or is the Court free to judicially amend the Constitution by interpreting public "use" as public "purpose"?
In case you are interested, here is a short (30 minute) video lecture in which I discuss the Great Debate--Originalism vs. The Living (Common Law) Constitution:

We will discuss quite a bit of Constitutional Law as it concerns private property in the Property course, but this video is not an assignment. I share it just in case you are interested in learning about the Great Debate about how to read the Constitution. And here are two good short articles on originalism vs the Living Constitution:

Finally, here is a quotation from Justice Gorsuch to the NYT (link) on his view of originalism:
So what originalism is, is just the simple idea that you are entitled to rely on the written words in the Constitution. We the people, the American people, bothered to write it down. Write down the law. It was the first written constitution of its kind in human history. And so when it promises you a right to a jury trial, when it promises you a right to confront your accuser, when the laws enacted promised somebody by treaty certain rights, an originalist, a textualist, will take that seriously. And there’s going to be no pragmatic argument, no argument from efficiency. Nothing that can undermine that. Now, if you want to change the law, there are lawful processes for doing so, but the originalists and textualists, simply put, seek to honor written law.
It seems clear to Justice Gorsuch that the duty of the Court is to follow the written law (as opposed to amending the written law).
