Same here. How plausible is this?
Not at all; the Iceland government had the interest and ruling of Iceland only. The other North Atlantic dependencies were ruled by plenipotentiaries!
Greenland was a colony prior to 1953; only the effects of WWII made for Denmark changing the status incorporating it as an Amt. Part of being able to sign the United Nations charter and stick to its part on decolonization.
Even if local Inuit/Greenlanders had been admitted to hunter councils (fangerråd) - local "governing" bodies that was about the closest thing to democracy in Greenland and nobody deemed them able to rule themselves.
Denmark wanted to protect the locals from foreing bad influence thus didn't allow anybody to enter except with specific permit.
So it was viewed as a piece of museum you had to protect and only gradually allow its inhabitants to govern themselves!
