Headstones are the ultimate flip-off to the living. Headstones deny real estate to generations to come. Collectively, cemeteries prevent agriculture, housing, and other benefits of the land. One's lifeless remains become passive aggressive behavior at its finest. A perpetual sit down strike and it takes a court order to move you.
That's why one side of me wants a big monument. The prospect of annoying people 1000 or more years from now has appeal. I'll be cremated, so there will be no one getting rich by displaying my bones in a roadside attraction. The monument has to be an obelisk with a particularly sharp point. Birds will be denied a resting place.
