This is crazy this showed up on HN. Years ago I had a dream about Pitcairn island. When I woke up I was like, does that even exist? Not sure how my psyche channeled this one up. Then I started reading about it and things are pretty sad there. You can see on the Wikipedia site some really shocking info like there's only one older administrator of the electricity system there and not to mention all the awful abuse scandals. It was super surprising to me though to see that foreigners were welcomed here and that more people hadn't taken this offer up!
I would say if you're interested in moving to an autonomous region I'd for sure check out Svalbard first, although they're undergoing climate change and it's hard for foreigners to get land there.
