baz_num_elts exercise from Software Foundations

Question

I'm at the following exercise in Software Foundations:

(** **** Exercise: 2 stars (baz_num_elts) *)
(** Consider the following inductive definition: *)

Inductive baz : Type :=
   | x : baz -> baz
   | y : baz -> bool -> baz.

(** How _many_ elements does the type [baz] have? 
(* FILL IN HERE *)
[] *)

All of the answers I've seen on the Internet say that the answer is 2, and that the elements are x and y. If that's the case, then it's not clear to me what is meant by elements. There are certainly two constructors, but it's impossible to actually create a value of type baz.

It's impossible to create a value of type baz because x has type baz -> baz. y has type baz -> bool -> baz. In order to get a value of type baz we need to pass a value of type baz to either x or y. We can't get a value of type baz without already having a value of type baz.

So far I've been interpreting elements to mean values. So (cons nat 1 nil) and (cons nat 1 (cons nat 2 nil)) would both be elements of type list nat and there would be an infinite number of elements of type list nat. There would be two elements of type bool, which are true and false. Under this interpretation, I would argue that there are zero elements of type baz.

Am I correct, or can someone explain what I'm misunderstanding?
