What is step 2? Normally, I would assume you try to minimize the incentives in buying stolen goods. In this market, nobody is above buying dubiously sourced oil, but what is the likely destination? Do the pirates patiently sit at the oil depot while the ship gets pumped dry, hoping the check clears and nobody shoots them on sight? Once you have an empty $100MM tanker, how do you unload that vessel?
Is it possible the Indian/Japanese/other-petroleum desperate government strike a deal with the pirates?
The era of blithely sailing around with $200M in oil or $1B of manufactured goods on a slow, totally defenseless cargo vessel out in the middle of nowhere and crewed by poorly compensated crews with nothing to gain for being heroic was a short-lived fantasy.
Imagine leaving a billion dollars in cash (or whatever) undefended in the middle of a desert, already conveniently placed in a mobile vehicle ready for you to drive off with. Maybe overseen by a couple of unarmed people you hired for minimum wage that aren't even trained security guards, they're just "staff".
What we're doing now globally is the direct equivalent, which worked for a while under the umbrella of Pax Americana, but that era is over, mostly thanks to one person deciding it's somehow "unfair" to the nation that benefited from it the most.

> It’s a very profitable business. We’re like pirates.
