I can't say I fully thought out my comment to that extent, but I do agree that we need proper regulations to protect us from shady business practices, even if the CEO in this case believed it to be safe enough to take the same risks as the customers. But that is beside the point. Proper regulations protects the public even in that case.
How those regulations could be enforced on international waters is whole bag of cats that I don't even have a shoot-from-the-hip kinda opinion on. UN somehow? I don't know.
You are probably right about game theory working for zero sum games, but in this game, there is only one player. Us. Humanity as a whole. The two outcomes in that game are so trivial that we don't need game theory to figure out which outcome is most beneficial.
We pretty much already know what needs to be done to win this game, or at least give it our best shot. Game theory is what holds us back from doing that, because we are wrongly applying it to try and find local best outcomes. Unfortunately, there is no point in looking for local best outcomes in this game, because they won't matter if the whole game is lost.
