That and the sometimes cringeworthy libertarianism aside, the business concept is quite interesting.
This couple planned to manufacture these homes in Thailand for about $20k each. They can then be towed out somewhere and raised.
While not in this video there's a unique team of Western volunteers and local manufacturers behind this.
Also interesting was their concept of building an artificial reef under the seastead, this is a simple but slow process, yet would help ameliorate depreciation of the home. Could easily imagine large movable artificial reefs to be quite valuable resources for anyone living at Sea.
