Long of the short is that if the law requires a front,rear or both brakes that's what you need. If you run brakeless then you need to HTFU and act like an adult and deal with it. Cycling with cars is not fair, just as life. Nobody in this world would ride anything with wheels without brakes and expect to come out on top in the case of a collision.
That said,I've run brakeless for 17 years and only had 1 time being hit. It was the old ladies fault but I just got up and rode home. No injury. I was lucky. If the law got involved I would have made my peace with it and chalked it up to me not following the law.
