Wild idea: I think we should turn Greenland into an into a new frontier nation with completely open borders for refugees and people who are up for the challenge of settling a new place. Sure, there's nothing there, but if you want to build something and there's nowhere else for you, have at it.
That could be a solution for the asylum seekers in the US, too... settle them in the Alaskan wild. If you’re willing to go from Honduras to Nome that’s a clear cut sign that what you’re fleeing is a very real danger.
To try to articulate why this is an unfair and bad idea, it's very hard to subsist on Greenland. Probably it would involve generations-long learning from those who can already subsist there on their own.
If we're not talking self sustenance, then the settling people would be supported by the existing civilization on Greenland, and it's already small, so it can not support that many.
Kanger has the largest road network in Greenland. I once got to go on the road to the ice edge, which was a wonderful experience. The ice near the edge is so dirty you don't immediately realize you've transitioned from dirt to ice.
You know it's tough to live or grow anything there now, but I wonder what climate change will do to the summer temperatures in 10 years. Could we see summer temperatures being warm enough to support agricultural crops.
EDIT: Out of curiosity, I started looking at Greenland on Google Maps and found this sweet shadow of the buggy they used to street view (dirt-road view) it: https://www.google.com/maps/@67.0111595,-50.7379435,3a,75y,9...
