Creating a Race

Ok, so when you select one of the pre-made races, you get 10 points to put into any of the abilities (+military, etc.). However I notice that even when you clear away the pre-set 10 points, the pre-made civs still have some bonus abilities you cannot get rid of. So, my question is, isn't it a disadvantage to use a Custom Race, because you only have the 10 points and not the extra abilities the pre-made races get? Or am I missing something?
