It&#x27;s obvious that moving oil in space helps, right? You move the resource from a place it&#x27;s relatively plentiful to a different place where oil is relatively scarce. Say, from the Persian Gulf to Australia.<p>The same thing is happening here:<p>These ships are trying to move oil from a <i>time</i> when oil is relatively plentiful to a time when it&#x27;s relatively scarce. It&#x27;s riskier, but if they succeed, everybody wins: they make money, and they do it by lessening that future scarcity.
