"In certain parts of the words" they arent even now.

True, but Baldur's Gate doesn't exist now and in real world. I would say that a more imporportant consideration is how Larian wants Baldur's Gate to feel. I don't mind exploring a bit more idyllic universe. But considering how much of an ass NPCs in BG3 are, perhaps they should become hostile not only if you try to pop in to say hi, but even if you loiter for too long in front of their property.
