What is the point of choice when both options lead to the same outcome?
If you want versatility then a blank human is the ultimate canvas as they can be anything you want, however if you are going to give the player a choice in races then you might as well make the choice significant by making playing each race a unique experience.
I think it is better how it is.
If you want to join the Stormcloaks you play a Nord, it is as simple as that just like in Origins your character cannot marry Queen Anora and become king if he is anything but a Human Noble. You said in your previous post that not allowing racial choice somehow "destroys the lore", however allowing a Dark Elf or High Elf to join and become an influentual member of the Stormcloaks is a far bigger kick to the nuts of the lore.
