Fishing in Greenland probably has little significance to Denmark's economy now, but in the event of some future political/economic crisis it's nice to have backup resources. Japanese militarism in the early 20th century was motivated by the fact the population there was growing faster than their rice production ability.
Admittedly if Denmark was suffering from genuine food insecurity then convoys to and from Greenland would probably be under threat as well, but I agree with the G that when food runs short every other consideration becomes secondary.

I get it, humans need food. If that’s your point I agree. That doesn't mean Greenland is a giant fridge to Denmark though. Other natural resources may have been and continue to be of interest to Denmark, but I'm pretty sure that zero Danes consider Greenland a backup food supply (even in times of crisis, which have occurred numerous times)
