Denmark giving transfers to Greenland increases demand for Danish goods themselves. It’s similar to Germans whining about them subsidising “lazy” Greeks. That’s not how capitalism works, under it spending of any kind can create employment, and imports by Greeks were financing Germany’s low fiscal deficit, since current surpluses were high while maintaining employment.

So under capitalism purely looking from “selfish” economic perspective :

1. Denmark gains demand for its goods form Greenland increasing its own output and employment.

2. Greenland gets access to more goods and services than it would be able to if it were independent.

This isn’t anti-independence, just that Greenland losing out on transfers will likely reduce its imports. But at the same time, Greenland having its own currency may also allow it to spend in ways it can’t currently ie improve productivity, employment so the loss of transfers may be somewhat offset.

Quite different from say, USSR giving transfers to Cuba. Since USSR operated under a centrally planned full employment economy, any transfer meant loss of resources but no higher employment (since it was already at full employment). Very different from capitalism.

In this case:

1. The USSR lost access to oil and other goods which it could’ve sold to other countries for foreign exchange or real goods/services while not gaining additional employment.

2. Cuba gained acesss to real goods from the USSR allowing it to have higher standard of living.
