... a multi-billion dollar per annum industry and beloved recreational past time? I do agree that prognostication is very rarely correct but the uses for the technologies in question go far beyond the political pipedreams of the seasteading society. If you could produce something equivalent to an RV for the sea you would absolutely have a market but with the major difference that the upper size limit on floating vessels is several orders of magnitude larger than that on land based vehicles. There is already incentive to use structures like this in cities limited by waterfront. Their uses recreationally as a summer home are extremely evident if you've ever seen a lake filled with houseboats [1], floating data centres [2] also come to mind as well as those barges that Google built. The biggest issue would be transportation to and from the mainland or between these structures but if they can be joined together at sea this problem quickly disappears as the number of connected structures increases. Beyond that, there is still the very real possibility that this could open up the last and widest frontier on Earth and we'll have gone from prairie schooners to seasteads. Also, with the increasing mobility afforded by a cell connection for phone and internet, there is a growing movement in the same vein as the original dreams for the future of the motorhome [3] I'd expect a seastead to more closely resemble a tiny house than an RV i.e. more house than vehicle, since people want to live in a house not a boat.
