Gimme some of that personal space..

I remember reading something on polygon, about people making lines in WoW Classic, to start/finish quests, as not to overpopulate the "personal space" of the NPCs.
Of course, that's a bit too much hardcore, but it should be used as common sense, that other people need access to that NPC, and you should not deny them that. And not just the interaction with them, but the whole "ambience" they were set onto.
I agree with BiddyBatnana that SOME people might be selfish to that point, where they do not seem to worry at all, as how they are affecting other people experiences.
The range for interacting with NPCs is quite enough to leave sufficient area for they to actually appear in everyone's screens.

If you use target filters (default key on keyboard is holding x) you'll click right through people and chocobos etc and only be able to select NPCs or objects.

Using the X key to interact with NPC's is a good and wonderful tool indeed, but my point was more aimed towards being able to see the NPC's when talking to them. Not being able to see them really takes away from the immersion imo. >.<

Personally I can't really blame people for standing too close or literally facehugging the NPC's because most people just want to rush through the quests to unlock the new content. That's why I think it would be nice to have this option to hide other players around the NPC's you're talking to, because then people wouldn't need to be considerate nor would anyone really be bothered by it.
