power cord directionality

Now I wonder why was it even bothered to be  labeled since it only connects one way..... (?)

So let me understand. are you saying vibration can have a negative effect  on how electrons flow? If you shake/vibrate any wire enough, it is possible to change the position of an electron?

In my opinion vibration can have an adverse effect on a connection point of a wire.

example: if you have a low quality outlet the physical connection between the plug and outlet may not solid enough and you may have arcing. Also the more valuable precious metals used in the plating (gold/silver) may offer higher conductivity.
