Unlike private property, eminent domain does flow naturally and inevitably from the concept that ownership exists only insofar as the state is able to secure and defend the territory. If the state needs your land for some public purpose, and you can’t raise an army to oppose the state, your land is forfeited. Living in a state that is willing to pay for private land it needs to take is just a modern invention for property owners who could otherwise get screwed if they happen to live on land the state needs.
