because once realid has significant penetration most of those other options will go away. the point of having one true ID thing is that they only have to care about these (and passports, which preserves the fiction that nobody is being discriminated against).
that said, realid is a pain in the ass... and it's security theater. at this point I have two (possibly three... I don't know if my global entry card counts as a realid) but i can absolutely see how getting a realid could be difficult for someone.
