The main difference is that the UN didn’t force anything and isn’t unilaterally deciding what projection to use. The countries decided together to use a new default when showing the world map, that’s it. You can still use whatever projection you want, nothing will happen to you.

That’s literally what the UN is for. The UN isn’t a supranational organization fixing conflicts. It’s a forum for countries to discuss and agree on things, in practice that means mostly symbolic decisions pass. Which is fine, symbols and defaults matter

This is kind of personally embarrassing, but due to seeing Mercator maps all the time growing up it wasn't until later in life that I realized that Greenland isn't actually a gigantic landmass the size of Africa.

> The value of a geographic projection is in its utility for the task at hand

Other than maritime navigation, I can't think of many tasks where Mercator would be more useful than an equal-area projection.

For the purposes I use world maps for, correct relative sizing is the paramount thing I'm looking for in a projection. I generally use it to give me a rough idea of distances. Boggs seems inferior, at a glance I have no idea how far it is from NYC to London, for example. I feel like Mercator is similarly bad in terms of distances being uniform. What do you use maps for where Boggs is superior?

Symbols are arguably the most important aspect of geopolitics.

The UN is a body that is intended to facilitate global cooperation. This symbolic change better represents the body's members and updates an incorrect visualization, which leads to better cooperation and representation.

Trump's renaming changes serve his own whims and selfish ego, they perform the opposite effect and hinder global cooperation.

It's not the most pressing issue in the world, but long-term, maps do shape conceptions about the world that we don't personally know. So it might be symbolic, but symbols are powerful.
