Governments can take your land through Eminent Domain if it is shown to benefit society as a whole.
By the United States Constitution, in the United States such a taking must be with compensation (reasonable, market-based compensation). And the same is true in most democratic countries with an independent judiciary. (This is notably not true in China, which is why seizing land from peasants is a favorite way for corrupt local officials to enrich themselves.)
Correct, I called out the provision that patents must be licensed at a reasonable rate in the attempt to draw the parallel with the reasonable market rate compensation for eminent domain, but left that portion out by accident. Thank you for calling it out.
