I basically agree and wouldn't want things to be changed in general. That being said, the choice of words in a novel should generally be governed by the artistic intent of the author rather than the desire to teach people stuff.
But here's an example that's worth thinking through. This movie https://www.imdb.com/title/tt0110428/?ref_=fn_al_tt_1 was called "The Madness of King George". It's based on a play called "The Madness of George III". They changed the name when producing the movie because of the difference between Britain and the US.
In Britain pretty much everyone would know that George III refers to King George III. However when they first started discussing this project in the US, a common reaction was "I haven't seen "The Madness of George 1 and 2". Now the differences between the titles wasn't that important and clearly this was just an impediment to understanding with no benefit.
Now you could say "Well the people could go on wikipedia and find out that there was a King George and a King George II and then this guy, George III" and that's true but the problem is negative self-selection. People who don't know that don't realise that's what's at play here and so won't do that search so nobody learns anything.
It's not particularly reassuring that "George III" (spoken aloud as "George the Third" ), and "George 3" (spoken aloud as "George Three" ) are apparently thought to be interchangeable in the US.
