Thai authorities have raided a floating home in the Andaman Sea belonging to an American man and his Thai partner who sought to be pioneers in the "seasteading" movement, which promotes living in international waters to be free of any nation's laws.
Thailand's navy said Chad Elwartowski and Supranee Thepdet endangered national sovereignty, an offence punishable by life imprisonment or death.
It filed a complaint against them with police on the southern resort island of Phuket. Thai authorities said they have revoked Elwartowski's visa.
Elwartowski said in an email Thursday that he believes he and Supranee - also known as Nadia Summergirl - did nothing wrong.
"This is ridiculous," he said in an earlier statement posted online. "We lived on a floating house boat for a few weeks and now Thailand wants us killed."
The couple, who have gone into hiding, had been living part-time on a small structure they said was anchored outside Thailand's territorial waters, just over 12 nautical miles from shore. They were not there when the navy carried out their raid on Saturday.
The Thai deputy naval commander responsible for the area said the project was a challenge to the country's authorities.
"This affects our national security and cannot be allowed," Rear Admiral. Wintharat Kotchaseni told Thai media on Tuesday. He said the floating house also posed a safety threat to navigation if it broke loose because the area is considered a shipping lane.
Seasteading has had a revival in recent years as libertarian ideas of living free from state interference - such as by using crypto-currency including Bitcoin - have become more popular, including among influential Silicon Valley figures such as entrepreneur Peter Thiel. Elwartowski, an IT specialist, has been involved in Bitcoin since 2010.
Several larger-scale projects are under development, but some in the seasteading community have credited the Andaman Sea house with being the first modern implementation of seasteading.
