PVP settings do have something to do with this, but aren't necessary. For example: I'm usually too lazy to go grab our butcher knife (on top of the fact that I never bothered to learn where we kept it) when dealing with the boars on our farm, so I just turn on PVP when I'm doing that chore then turn it back off when done.
