But, what about the costs? What he proposes sounds great and all however I can't imagine anyone who doesn't have the money to buy/build a floating house being able to at all. Perhaps on the ocean, if someone doesn't like their current situation they can just float off and find a new one, but how does one initially 'float off' and start seasteding? Beyond that what about things like luxury goods, medical supplies, how would they be supplied? I'd imagine that these wouldn't be supplied for free from nations and corporations, and until these oceangoing cities become massive enough in scale to produce them on their own, they need to get them from somewhere. While I do agree that the idea is fantastic, I must also agree with what Grendel said, there are problems that need to be addressed too.

I do nothing, I sleep, I waste my time on the internet, I regret all of that, and I rinse and repeat.

Who's making all these predictions exactly? I can't find anything. Perhaps I just didn't search hard enough though. Regardless, this is a very interesting find, thank you for sharing!
