Of course, many people are going to argue these individuals are addicted. I would question this idea of addiction strongly. Are these people really physically compelled to steal bikes, and, in so doing, plan the theft, hide the bikes, avoid the victims, etc., by the drug, in order to acquire it, I doubt it. Only consider all the addicts who do not do this to see these thieves have free will. Hence, I would argue for the rigorous treatment you propose. Sometimes tough love is best.
