> within region of the sea where Thai government has the final say.

They are beyond 12 miles, this region is not territorial waters but international. They don't have the final say, except in matters relevant to their customs, commerce and artificial islands. If this was in a sea shared by two nations, i m sure the situation would be a lot more complicated.

Also, this was more a statement rather than a realistic seastead. The cost of the tiny seastead is ~$150000. Hopefully more will follow which will lead to a larger discussion about governmental overreaches.
