South American natives have brown skin, that is great, because they live near the equator, and as we've established before, that makes your skin more likely to gain color, check, you made my point.
If we get to see more about the men of the east that would be great, the inclusion of racial elves and hobits makes me doubt we will though, but I could be wrong and that would be good.
Fantasy doesn't mean you get to disregard internal logic, if you are familiar with Tolkiens works, which I can see that you are not, the history of middle earth was written as an alternative British history, as such it's set in northern Europe. If further draws inspiration from Scandinavian folk lore, and having a black elf in Scandinavian folk lore is about as racially sensitive as having a white witch doctor in a movie about the Zulu.
Further, if your work of fiction is shown to be a work of fiction it loses entertainment value for many people, the secret to a good story is, the author is always in control, if you want to you can end any story or conflict with a single sentence, the key to great writing is to do it in a way that the audience forgets that the author is there.
We all know that the script writer decides if the protagonist of any given story lives or dies, but a skilled author or movie maker can make you forget that.
About your final point, yes, trade is very lucrative it's in fact very very lucrative, that does not mean you get villages set in the middle of the forest with different ethnic makeups. You try traveling China at some point, the very place where the silk road originated from, and I'll tell you as someone that is Chinese, once you get out of Beijing/Shanghai, you will have a hard time finding foreigners, instead as you travel east you will find the racial makeup slowly shift, but you won't find villages of people just randomly being half inner mongolian half han.
I also mentioned port cities in my original post which you conveniently left out, as you know it rendered your argument impotent, because that is how most trade was carried out over vast distances.
