Right, like when the UK left the EU.

I'm not sure they're really that different at a high level. The population of Spain would vote against Catalonia leaving. The population of the UK would vote against Scotland leaving. How can these groups (Scotland and Catalonia) self-determine to leave?

The UK literally let Scotland vote on it [1]. On the other end of the spectrum, Greenland is a proposed military invasion and unilateral annexation.
