Maybe not if you're an actual outlaw but as a privateer marriage is basically your only method of societal advancement; if you're a naval officer then most likely you are already a member of the aristocracy and marriage is a valuable tool for gaining more wealth or cementing family alliances.
I don't think the game needs marriage but to say it's not important is ignorant.
