Naw. I think it does. Your complaint about what I'm saying is the same as if I were to say, "Dude, no one is going to start re-printing the PHB until it is up the 'correct number of race standards of gyor' so your thread is a non-starter."
As I wrote, races serve only two real purposes in the game. Mechanical (a collection of bonuses and abilities) and roleplaying (a collection of stereotypes traits for a race).
You could accomplish the exact same thing by having variant humans with those abilities.
So the question is, why? Why bother with these races at all? After all, many games don't need it. And you could play D&D just fine by re-skinning every single race as human.
There's really three reasons, then. The first is tradition. D&D has classes and races. It always has, and therefore it always will.
The second is a variant of tradition. Fantasy games (aka Tolkien-y games) have fantasy races. People see LOTR, people want to play Legolas. Especially Brad. You think he'd change it up, but no, every single time, "Hey guys, Ima play an elven archer!" "Yeah, we know."
The third is a variant of the second, wish-fulfillment. "I want to play an Elf, because I want to imagine myself as an elf." And so on.
So D&D will have the PHB with the core races (and the core classes) that appeal to the greatest number of players (your standard core fantasy/D&D races), and then will push out additional material for people that want it.
But yeah, a lot of the issues revolving around races (and RPing races) can be ... weird ... after a while. Which is why I prefer anthropocentric campaigns.
