@GM4Him Some really good points raised when it comes to narrative context of Larian's map design. I am not sure much can be done about it aside from "suspension of disbelieve".

Larian wants "open worldish" (single map? Open map?) design for gameplay reasons, but doesn't support it narratively. Generally open locations like that tend to be supported narratively (prison in Gothic1, Deus Ex/Thief where the character doesn't have a reason to venture outside given area). I think it is just another way in which Larian's RPG tend to lack cohesion.

This particular thing didn't bother me that much thus far, but perhaps it's one of those things because of which I see BG3 as artificial game space, rather then world I am exploring.
