I think , as for me personally, I would rather look at 10, 11, or 12 hockey pucks stacked on top of one another pushed against a wall, or slightly out from the wall, than see an anchor above the outlet with a Zip tie hanging from it. That’s just me though.
Heck who knows, Hockey Pucks glued together may absorb vibration from the wall outlet, plug, or cord. You know like them expensive carbon fiber wall plates do.
Hockey Pucks come in different flavors too. Black seems to be cheapest though.
