I guess that sort of makes sense, but even then DD's Liberator from 8 years ago was a far better option to go for here.

"better option" in what possible way?

I'm very sorry to say this homemade gun did exactly the job it was intended to do.

Terrible news. :(

You're forgetting that he also had to make his own ammo. A black powder shotgun is the easiest firearm to make from scratch if you have that constraint.
