Philosophers and legal theorists over the centuries have have come up with the concept of "proximate cause" (https://en.wikipedia.org/wiki/Proximate_cause https://en.wikipedia.org/wiki/Proximate_cause) for these types of discussions. Essentially, there was recognition that ALL kinds of things could be seen as connected to a bad thing. But for the miners, we would not have extracted the iron ore that was used to make the steel that was used to make the firearm that was used to shoot the victim, etc. So "proximate cause" is a discussion of whether or not the degree of connection is close enough to make the blame ridiculous or not. Not really taking a side in this debate here. Simply pointing out that just coming up with a slew of "but for" causes is not a libertarian trump card for everything. Societies and systems can rightfully draw the line somewhere more reasonable.
