Thanks.
I guess those Bajao structures (Bajaos are the Philippine sea gypsies) are floating directly on top of the water surface, so they are very exposed to wave action, so usually they are close to the shore, protected by a reef for wave breaking.
The spar construction of this seastead is more similar to an oil rig.
By changing the buoancy of the spar, the house on top of the spar can rise up higher above the waves, if the waves become bigger.
So it can be further out in the ocean.
This one can rise up to 5m above the water surface, but in the Andaman sea, average wave height is just 0.5 m, that was also one of the reasons, they put it there.
To be really out of the reach of a nation state, at least theoretically, you need to be outside of the 200 nm zone, so you need a spar which rises high enough above the sea level to withstand the wave action of that area and you need a seamount or the bottom of the sea shallow enough that it is still feasible to anchor your seastead to the bottom
