Most resource guarding is fixable. To me, saying you don't want to live with a resource guarder is almost like saying you don't want to live with a dog that isn't house broken... It's fixable, so why get rid of the dog just because you don't want to put in the time to fix the issue? (Granted that a dog not being house broken doesn't involve biting.) Also, I see a HUGE difference between resource guarding and flat out human aggression.
