Yes. There have been threads on this. In a nutshell:

  1. Prepare to lose your claim of soverignty as soon as your claim buts up against the will of others who also declare soverighnty over the same land (e.g., the United States); and

  2. If there are no opposing claims… Google “Sealand”

You may need to fight a war over it.

Indeed. I’m pretty sure there was a skirmish or two around the 1860s.
