It's a very dumb joke , making fun of a dumb tv show call the good doctor. The writers decided to write a show about a young autistic surgeon, and also decided that his only personality trait would be being a surgeon. There is a scene where he is fired, has a mental breakdown and keeps yelling " I am a surgeon".
Mostly a dumb joke, making fun of writers who wrote the main character of a show based solely of one idea, with no character at all.
He is a surgeon He is a surgeon He is a surgeon
I think it's stupider than that. They have no idea how a handmade gun could be built without a 3d printer. They probably have zero clue what a 3d printer actually can and cannot do, and I'd bet most politicians have never seen one or bothered to understand it before regulating it. Their sole exposure is a few loud people who also do not understand anything about guns or 3d printers, and confuse that lack of understanding with definitive proof that it is evil and should be banned.
I know exactly why you never see UFOs. Turns out, humans are pretty good at identifying flying objects.
As a non realistic version, have you played timber born? It's about beavers making dams and towns, but very much not realistic.
