Yeah, you definitely need a semiautomatic rifle capable of firing dozens of rounds in rapid succession in case hordes of ravenous beasts descend upon your farmstead 
If that was really what gun ownership was about, then no one would argue with banning handguns or AR15s. The UK has very reasonable rules allowing ownership only of sporting rifles and shotguns for hunting. If it was about hunting and protecting your property from wolves and bears, that would be MORE THAN sufficient.
