I want to point out, that manufacturing a gun is not "non-trivial".

Given blueprints, (publicly available) or a template and accurate enough measures, a lathe, and a mill, anyone can make a firearm or parts for one in their garage.

Is there reading involved? Yes. But any argument you make w.r.t. The futility of illegalizing encryption is immediately portable to firearms manufacture.

I mean... manufacturing a working modern firearm in their garage is probably much more achievable to the general population than rolling out any kind of encryption software. Anyone with some basic hands-on competency can make a gun.

All you really need is a drill press and some basic tools. People made Sten guns in WWII and that's still a perfectly valid firearm design (fully automatic even) that requires almost no work to make.
