The key term some people never learned in school is "direct democracy" vs. "indirect democracy".
Even many clubs, e.g. in Germany the ADAC, have systems where people vote for an assembly (or, in politics: a parliament). And then the assembly vote fot ehri CO (or, in politics, for their chancellor). Now, it can happen that this chancellor together with 26 other head of states is a member of the Europen Council (EUCO, one of the 7 bodies of the EU, what btw most people all the time intermingle). And that this EUCO now votes on their president.
In your logic, this presidency of the EUCO is then null and void. Because not directly elected by citizens of the EU.
In my logic, I realize that this position is removed from the people, but it still done by a democratic process. A multi-stage process, but still democratic. And that it still has some bearing.
Asking for the whole world population having an election on e.g. the UN Secretary General --- under the implication that only this would give representation --- is bogus.
I implied instead that there is a crisis in representation.
(...You could be German and you have not noticed, in spite of all the vocal effort in the North? That and all the other similar signals clearly affecting current history.)
No one is forcing you to use the new map, you can keep your old map. No one will arrest you for it. Enjoy!
Also, the UN voted to use this map for itself and suggested (!) that others should use it. It never said that everyone has to use that map. It actually said that this voting is "non-binding".
