Even when I'm home alone I close and lock the bathroom door. What if someone breaks in while I'm exporting goods through my southern border? Major disadvantage.
It would be just as embarrassing (if not more so) if you were caught importing goods through that particular border. A locking door would certainly prevent the payment of "reputational tariffs"...
I'm building a tiny house on The Sunshine Coast in BC, so I have somewhere to live...I also have no idea what I am doing...
