You are confusing a lot of things.  I merely wanted to say that [(meta q)] should be [(meta ?q)]: ?q is the character; q is not.  Other people have mentioned other, orthogonal corrections.

Yes, (kbd "M-q") is perfectly clear.  No, there is no advantage in one's init file to using [(meta ?q)] instead.  No one suggested otherwise.
