A person's right to throw their fist around ends where my nose begins. If someone robs me to get the money they need for their addiction it is indeed my business. If their addiction causes them to lose control of their car and damage me or my car, then that too is my business. And if their addiction causes a strain on society that I am a member of then that too is my business. A person should have unlimited freedom only up to the point that it harms someone else.
