I agree, but I'd rather not turn my back on any antagonist with a knife. As another commenter has said, a 95% chance of getting stabbed are rather crappy odds.
Neither would I, but there's a lot of sick fucks out there and there's no telling what they'll do if they have you in a submissive spot. I particularly don't want them knowing where I live. Plenty of people have gotten killed because they got robbed and they didn't have enough money to satiate the thief.
