No, it's good to be able to create a thing without using it.
We do it all the time with variables, for example.

        void foo()
        {
                int may_be_used;

                if (some_condition) {
                        may_be_used = bar();
                        if (may_be_used)
                                baz();
                }
        }

Wouldn't you hate to have to structure your code so you only
"executed" declarations of those variables you actually used?
