The difference between someone falling on a knife versus being stabbed is evident (even to me).

I think a more interesting scenario is the case of a "criminal" in an AC world who is not locked up but who can't find anyone to transact with him because of his criminal past. Now, the "AC citizens" (slight misnomer, but I think you'll know what I mean) aren't really aggressing on the criminal with violence. But if the guy starves to death or is eventually shot for trespassing because he can't find anywhere to go, well then it didn't make much difference to him that the citizens killed him in a passive way rather than an aggressive way. I think there is a richer debate to be had regarding this situation where the intent is to exclude the criminal from society, and even though it is done passively rather than with violence aggression the intent is still the same. The outcome here isn't accidental.
