Of course more money
My recollection (I don't have a citation, but I am pretty sure it can be located quickly) is that the $5 per person has no impact on the actual cost of security, which is about $80/person. I am not so sure that Joe Sixpack is as stupid as people say. But, if we charged $80/person (and let everyone know that it was going to $100/person to cover new technology) I wonder how people would feel?
