If we cite potential RMT abuse for the reason every time we can't have nice things, then we wouldn't have much of a game, would we? I mean heck, might as well remove the mail system, market boards, and ability to gather our own materials too.
All I know is this. When sellers have a full stack of items, they want to sell it all at the standard market price for 1 item x 99. But they can't because, a lot of the time, it is greatly discouraged as there are many items that buyers only need a small handful of, like raw gems (i.e. Ruby, Sapphire, Rubellite, etc.).
I know that, as a buyer, I personally would LOVE to only buy what I need from a stack of 99 HQ Fire Rocks.
