"One man's wild dream." Bleh. Flowery words for yet another bunk propertarian sea-steading project. I mean, he was literally planning to mine the shit out of the ocean floor and sell away more of the ecosystem to the capitalist market in order to create his Utopia. At least there was some acknowledgment of that at the very end.

Very glad the opportunistic scientific exploration happened along with it, though.
