Ohhh man good question... soo much to say...

I think if all elves were free to do as they like they might still want to take care of everyone... it might just be something they like doing... but I think they would help on a vastly larger scale if they were all free to do as they please... But I agree with ^ a lot of houeselfs are short so things would need to be sized for them and all... I had somthing else to put here but as of this second I forgot it sooo....yeah I will comeback to that later...

You know what would be cool... If a house elf made it really high in the government and what not...
