More on Kelo vs City of New London, from Elighten NJ
From their post, All For The Greater Good:

Fast forward to the present and we find the constant erosion of property rights in the United States. People and their property are seen as little more than tax targets to be exploited for the “greater good”.

Look no further than income tax laws imposed; more for the purpose of wealth redistribution than to provide for the common protection of life and property of citizens. You don’t decide how to use the fruits of your labor; the “government” decides and demands to be paid first, to hell with your needs or wishes. All for the “greater good.”

The IRS has the power to investigate your personal activities and finances; without a search warrant the IRS has the right to search your property and financial records; and without a trial, the IRS has the right to seize your property. All for the “greater good.”

Find out how this erosion of the right to own private property relates to the Kelo decision by reading their post.

And while you're at it, bear in mind that nowhere in the Kelo decision does it say the property seized must be limited to real estate.
