You have been sentenced to life in a micronation of your choosing (Sealand, Molossia, etc.) The micronation must have actual land and you may never leave that land. What micronation do you choose?
Edit: clarification of the rules. A micronation is by definition not recognized internationally. As a result, small sovereign states like the Vatican are not allowed.
Also you can’t just make your own micronation wherever you want. It has to already exist.
This kind of makes the concept of a micronation useless. The point is that anyone can make their own nation with their own rules wherever they are or go. If you have to pick someone else’s, then it’s no different than picking someone else’s recognized nation.
