The EU (plus some non-EU members like Norway and Switzerland) has ESA
as its space agency. This all makes sense, as European countries are too small to effectively run independent national space agencies.
With that in mind, would it make sense for space agencies around the world to merge? For example, why does the USA and Canada have separate space agencies? They are two culturally very similar countries with good relations, and to me it looks like a net win if NASA and CSA
merged. It would mean more resources, and the combined space agency would have access to talent in both countries.
Another thing is, that when humanity eventually starts to seriously colonize space (maybe a few centuries ahead), I'd think it to be a positive if humanity as a whole did it, rather than various countries competing with each other to grab as much extraterrestial land as possible.
What do you think?
