Yes you are missing something. The topic was carrying a firearm inside a post office or on postal property under the Bruen decision, not an unloaded firearm packaged for shipping IAW other postal restrictions. Bonidy challenged his alleged right to carry a loaded gun, very different issue.How can one ship a long arm from a Post Office (legal) if having a gun on Post Office property is illegal?
Maybe I missed something.
Bruen was about carrying a loaded firearm away from your residence for self defense purposes, read Bruen and the Bonidy briefs, and you will understand. Totally unrelated issue.
