Maybe I need to clarify my position:
I’m a firm believer in “thermoeconomics”, the belief that the value of all things is deeply connected to the amount of energy required to create them.
I think that the success of an independent seastead resides in the interface between it and the sea: the breakwater. A small size swell produces 10kw/linear wave crest meter. You’ll need 10x0.2(conversion efficiency)x0.2(Capacity factor)= 250m2 solar panel to equal this on a 24/7 basis.
My point was that a sailboat/Oasis of the Seas/Floating retirement community is not a “seastead” because it is not an independent economy, because it doesn’t produce more than it consumes.
Of course it’ll need customers, those customers are gonna be on the mainland and they’ll have access to the ease in transportation and energy economy of scale it provides.
Without a way to put the energy of the seas in our pockets, there wont be no seastead…
