If “possession is nine-tenths of the law,” what are the points it outweighs?

The expression “possession is nine-tenths of the law” is from the eighteenth century and means that in the pursuit of justice possession in a dispute over property outweighs these nine other essential elements of a good court case: a lot of money, a lot of patience, a good cause, a good lawyer, good counsel, good witnesses, a good jury, a good judge, and good luck.
