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.
Technically so is sealand though, the UK and Germany both had to recognise it at different points
Not currently recognized though, so it still counts
