The comment you responded to literally gave an argument about where the line could be drawn. Do you not agree? I see this "where do you draw the line?" question asked a lot, and it seems that the usual intended purpose of it is to somehow give weight to the idea that it's too hard to draw a line somewhere and therefore we should maybe not even make the attempt. The fact is that there is an entire legal system we have set up to "draw the lines" on a huge number of ethical issues, and on top of that we have a whole world of extralegal organizational policies that can be argued back and forth. If you think there should not be any laws or policies concerning public safety on a particular issue, make an argument for it. Just because it is difficult to write policy or laws that take into account the right balance of freedom and safety doesn't mean we give up entirely.
