Pre-existing tiny nations are grandfathered into the international legal system thanks to, well, their pre-existence. Also, almost all of them are either (1) already bowing to the will of their bigger neighbors (e.g., all Caribbean micro-nations and the US, Georgia and Russia), or (2) in the middle of nowhere that nobody cares about (e.g., Nauru), or maybe both.
If any "seastead" gains traction and it becomes enough of a problem to, say, the US, nobody would even need any missiles. The US will simply declare it being illegal (for everyone) to do any business with these people. I hope the seasteaders have experience in subsistence fishing - they will need it.
