Yes. Why do you think I got married? I need my wife’s family to back me for the blood feud with my neighbors over his McDuchy (which de jure belongs to me) that’s been ongoing for 3 generations

Marriage predates the feudal system

marriage is older than feudal which makes it patriarchal

it’s an institution that dates back to when people were legally owned by their dad

although the concept of it being bad to murder your neighbour also dates back about that far so that isn’t necessarily a criticism
