That's somewhat true. Government does have the power of eminent domain to ram projects through if they want to (e.g. much interstate highway development). However, the willpower to accomplish may rightfully be tempered (e.g. fatal opposition to interstate spurs in many major cities). A state government, using eminent domain, reserves the right to seize land for "public use", which especially includes interstate highways. A "public use" project providing real, tangible benefit for a region without unsustainable cost burdens for the governed should go through, full send.

That's not to dismiss the value of local advocacy but merely to highlight the careful balancing act performed by government to maintain favor in eyes of its constituents. The fundamental tension between the People and the Government should err toward the People, as long as you place stock in a government "of the people, by the people, for the people."
