Pronouns are meant to be a finite set, contrary to names which are an infinite (or unlimited) set.
That way you can group many multiple names under few pronouns.
If you want to allow an infinite set of pronouns you might just as well remove pronouns altogether as they would stop serving the purpose they are meant to serve.
