The real point here is that you can't really predict where a company may choose to locate, and in the absence of regulations, you can't really assume that a company will choose to do one thing or another.
You also can't really predict if the government will decide a new aluminum factory is good for the economy and jobs, use their eminent domain power to pay "fair market" values to home owners, and kick them out whether they want to or not. So sucks both ways.
