Acquire Slice: The Game Theory of Forced Partial Acquisition
Eminent domain.
In most countries, governments hold the power to take private property for public purposes — a highway, a dam, a railway — and pay what they determine is fair. You receive compensation. You don't receive a choice. The state decided. The state is taking it.
Most people find this unsettling, even when they accept the logic. But at least the shape is recognizable: a government acts, a legal process unfolds, there's a stated reason, and eventually the thing is settled.
Now imagine that power without the government. Anyone — your neighbor, a stranger, someone a continent away who wants a piece of your territory — could take a slice of what you hold, pay you the market rate, and you couldn't refuse.
