Yes, property owners will then be viewed as potential terrorists, I'm sure. The government will then make sure to send in heavily armed LEOs to let them know they have 30 days or whatever to pack their stuff and get out.
Like auboy said, most of us can get good legal help, and I'd sure as hell be on the phone to the State AG's offices, Senators, etc., among others, saying "these people want to take my land and give it to Wal-Mart or whatever, so they can save a few minutes off their travel time, and the city can get a bit more in taxes, are you going to help me or do I need to go elsewhere (and mention you didn't help me, election year is around the corner)".
The whole point of the government in this country, from federal down to local, was originally to protect individuals. Funny how times have changed.
What's amusing, you won't find any big name celebrities or types like Jesse Jackson helping these folks.
