It is a type error at generation! Instead, I'm dealing with that case at literally every one of* thousands of places where I might receive it*! That's not clean.

It is. Just like 0 is a natural number, the empty string is a string, the empty set is a set, etc.

If you've worked with mathematical proofs before, you'll have experience with how they make proofs shorter and more elegant.

That's why they're natural base cases.
