Reasonably certain most people in the Abyss would like him to move to his own country.
That is the main problem with sovereign citizens, they are typically occupiers on foreign soil. Seems to me that, unless they have visa agreements with the nation they are residing in, they could be deported.
Not exactly sure to where, the only truly neutral place would be Antarctica. Sure, the moon or mars are options, but very expensive options. Much cheaper to deport people to Antarctica. Plus from an ethics point, at least there is the possibility of survival in Antarctica. The other two spots, we’d need to provide them with a space suit and a really huge bottle of air…not sure about water, if Nestle gets its way, water will not be a universal human right. Pretty clear from mass starvation that food is not currently a right.
So Antarctica seems best; and before long, it’ll have excellent vacation opportunities, the SC’s can stake out all the future beach front property and make lots of money.
Of course with so many SC’s it could become very chaotic once enough are down there, it would sort of be like Eternal War ala Warcraft….
