Piracy, on water, is our species regulating itself, in a habitat that is not our own. You can make piracy meaningless by no longer going there (the sea).
Obvious reply: What about the people whose lives depend on fishing?
This 'need' confirms that we have overpopulated the planet; and respectively, confirms the 'need' for piracy and war.
Everyone is doing exactly what they need to do. Why would we want to stop them from doing what they need? They came to earth, to this body, for the purpose of learning exactly what their life as a pirate will teach them. We must feel compassion for them; they will never reach awakening this way. Likewise, we must feel compassion for their victims; but also realize that they too- had a lesson to learn.
