What value does this add to its users? Most of the rich want extreme privacy, they do not desire to life in villages or cities, they want lonely towers on fort like islands or remote bunkers with a view. Here they do not get this, but they have the same costs as a normal yacht + tax costs to maintain the greater whole. It does not even provide decoupling from all forms of society, as the underclass necessary to maintain the vessel could rebel. The turtle moves, back to the drawing board.
