I would imagine that this system would greatly use the ocean as a resource (obviously). In order for this to be worthwhile, we would really have to not only design cities that floated and looked awesome, but also make sure that we aren't destroying the ocean. We are greatly affecting this valuable asset to human life as we are living now; I can only imagine the harm we could potential cause if we built our cities on top of it.
