Seasteading

Sea-steading is a lifestyle of making the oceans, or at least water-borne craft, one's home. Most sea-steads historically have been sailing craft, whether perhaps demonstrated by the the Chinese Junk, modified canoes of Oceania, or even the famous Pirates of Libertaria. In modern times in the west the cruising sailboat has begun to be used in the same manner. The term sea-steading is of uncertain origin, used at least as early as the turn of the century by Uffa Fox, and others; many feel that catamaran designer and historian James Wharram and his designs represent ideal Sea-Steads. More recently, American sailor and ecological philosopher Jerome FitzGerald has been a leading and effective proponent of Sea-steading, mostly teaching the concept through the environmental/sailing organization "The Oar Club". The Seasteader's Institute in Hilo, Hawaii offers classes, boat-building opportunities, education in forage foods, diving, and other aspects of a Seasteading lifestyle.
Some theoretical seasteads are floating platforms which could be used to create sovereign micronations, or otherwise serve the ends of ocean colonization. The concept is introduced in a paper by Wayne Gramlich, and later in a book by Gramlich, Patri Friedman and Andy House, which is available for free online. Their research aims at a more practical approach to developing micronations, based on currently available technology and a pragmatic approach to financial aspects.
The authors argue that seasteading has the potential to drastically lower the barrier to entry to the governing industry. This allows for more experimentation and innovation with varying social, political, and economic systems. Potential business opportunities include data havens, offshore aquaculture, and casinos, as well as the gamut of typical business endeavors.
