> a rugged community of 2300 people

I wouldn't characterize it like this. Longyearbyen has schools, churches, a post office, a local elected government. Kids play hockey near the streets over summer. Adults open museums, galleries and cafes for tourists. They've incredibly high speed broadband, amazing plumbing infrastructure too. It's an emotionally tough place to live over winter for some people, with the darkness, but it's not some Arctic campsite where only the rugged and tough can survive. And if you get ill you can easily go to the local hospital, with the possibility of a transfer to Tromso if it's bad.
