These kinds of places can look idyllic until it’s 5:30pm on a Friday and the only place to get a drink closed half an hour and the streets are all empty. Then they start to feel pretty boring.
Idk about greenland but in faroe and iceland a surprising amount of people are moving in because its a very calm place. The birth rate is also good(at least on iceland, idk about faroe) so the population is actually growing pretty steadily.
My in-laws retired and moved to France, in the rural south. It is eerily quiet because no traffic goes near their house, and they are 30 mins drive from anything like civilization. They do have a small restaurant (that loves putting froe grais on everything), a hairdressers, a travelling doctor, and (weirdly) a bowling alley that doubles up as the local bar and a place to buy stuff - all for less than a hundred people.
You can get really remote in the UK too. Some parts of England are 30 mins from anything like civilization. Some parts of Scotland are only accessible once a day by boat, and if you go really up north you find wooded areas where people die because you're surrounded by miles of nondescript woodland.
I've always had an obsession with maps, which as an adult has brought me to wanting to visit the "extremes" of the world. Far north, far south points of things. But I'm not the adventurous type so a lot of those places are just never going to happen. Nuuk has always been high on my list of places that would be neat, while not being impossible to get to comfortably.
