I believe they’ll eventually come for those too.

IMO the real end goal of these laws isn’t to ban ghost guns, it’s to ban plebs from being able to build or create anything at all. 3D printing a plastic piece to fix a broken tab in some gizmo cuts into corporate profits so a manufactured moral panic about ghost guns appears. I’m sure they’ll eventually get to a pipe rifle moral panic at some point to lock down DIY plumbing.
