While our oceans already face a huge amount of stress from climate change, plastic pollution, oil spills and over fishing, how can proposals for sea floating dwellings be sustainable or non-threatening to marine ecosystems?

Seasteading, the concept of creating dwellings floating at sea, colonizing oceans and bypassing territories controlled by governments, has been around for a long time. Floating structures anchored in international waters, beyond the "territorial sea" of any country, have included refitted oil platforms, modified cruise ships, or custom-built floating islands and structures to name a few.

Jacob Hurwitz-Goodman and Daniel Keller’s film The Seasteaders documents the first Seasteading conference in Tahiti, talking with Seasteading evangelists like controversial author Joe Quirk and Seasteading Institute executive director Randolph Hencken to get firsthand accounts of the Seasteader’s beliefs and visions for an aquatic future. While much remains to be worked out, not least of all the fundamental problem of the place of “shesteaders,” the Seasteaders hope they can float on changing tides as they colonize the world’s waters.

Founded in 2008 by former Google software engineer Patri Friedman with financial backing by PayPal founder Peter Thiel, the Seasteading Institute envisions a fluid world, where governments are selected in an open market and climate change can be “hacked.” Seeing rule by the majority as ineffective and oppressive, the Seasteaders propose a libertarian future of floating micro-governments, where user-citizens can detach and rejoin at will and law looks less like constitutions and more like software. To implement their plan for a nautical future, the Seasteaders have begun working with the government of French Polynesia to build the first floating islands in a special economic zone off the coast of Tahiti, after facing large-scale public opposition in Honduras.

Seasteading evangelists, in a similar way to Silicon Valley techno solutionists, are presenting the society as a system that can be modified, managed or controlled. A group of entrepreneurs proposes to create new markets and worlds that fit their needs for a rules-free society. But while these initiatives present floating societies as solutions to housing needs, environmental challenges or a way to escape badly governed nations, how can we know for sure that these sea structures are more than tax avoidance bubbles or extravagant retreats for the rich?
