I would, and my vote reflects that fact.Would you play in an RPG without human PCs or NPCs?
HOWEVER, in my experience, unless the presence of playable humans makes no logical sense (say, roleplaying in a setting where all characters are regular sized bugs), many players want to have humans as a playable option, even if they have no intention of playing one. Several players I know personally have balked at the thought of not having that option.
I think it’s sort of a comforting touchstone for such players. I sincerely doubt that it’s even conscious for some.
