Also Calico Jack, Anne Bonnie, and Mary, operated for 1 year and failed miserably at the end of Piracy.

I'd say some of your LIMITED examples of pirates in it for greed....were the biggest failures.

They were pirates because they operated independent of government law and were often punished for it by their own governments.
The pirate Republic born in Burmuda fought for independence from England, not treasure. Though as Vane tried, they tried to finance their state with spoils and plunder.
Lord Admiral Nelson captured more treasure in his victory at Battle of St Vincent than all pirates captured in the entire history of piracy.
His entire crews of the rear guard of the British navy (3600 men) became millionaires that day.
An unheard of feat never again accomplished.
