Okay, so you're good with treasure, but that's not really enough to call yourself a pirate. You commandeer a ship, not buy one. You force your crew to sign a pledge of allegance, you don't pay them off. Just because you're a rich plantation owner having a mid-life crisis, doesn't mean you can suddenly go rogue pirate and expect people to take you seriously. Being a pirate is about being a smelly, nasty, evil, bloodthirsty, horny bastard. You just don't make the grade. You're the equivilant of a Pirate Nerd!
