There's a pattern in forgotten realms worldbuilding, "all x are like this" but in exceptionally rare cases forget everything we've told you about how everything works. They philosophically don't believe in saying you, the player, can't do something, that's cool, but there's a problem when all these exceptions to the rule are always in games set there even without it being the players choice.
Games, as well as stories in general, tend to take place during exceptional times. Exceptional times tends to attract exceptional people.
To my knowledge there's never been a Forgotten Realms game where you're playing a halfling farmer working on a ranch in which nothing interesting happens. Statistically speaking there's probably tens of thousands of random farmers for every adventurer, but somehow every game is about adventurers.
