sounds like a good opportunity to bring back "letters of marque." These were less about authorizing ships to fight back against pirates, and more about authorizing private to your army to find and capture pirate vessels with the expectation that they would be allowed to keep whatever loot they captured. sounds like we're taking a step in that direction as the Internet is being identified as Lawless as the sea.
