Understood! I don't see anything invalid about what you've said. It's one of the drawbacks about monstrous races but that doesn't stop people from wanting to/enjoying playing as them. I'm inclined to think there are ways it could work (As I mentioned, Disguise Self, etc. A hobgoblin stopping the other goblins in the first encounter could potentially be an excuse) and I would point to Shadowhearts reaction to a Gith player character as an example of talking your way out of immediate hostility.
Slightly related, I've noticed a lot of people concerned about the story from the goblins perspective not having enough 'draw' (This is arguable but not necessarily the point I'm hoping to address here), Playing a goblinoid could give you more options to explore their side of the conflict. (Going all in for an evil playthrough)
If Larian can find a better evil route where you can realistically play a goblin? Sure!
Just right now it’s hard to do. And I don’t know if Larian would want to completely cut off a whole section of the map because of a race choice.
