The people you mention are still a product, and not something fixed on its own; more importantly the law deals with them as much as it is considered cleaning to throw things under the bed.
The rule of law protects peoples' rights. Without it, brutality reigns. At best, without the rule of law there is corruption, waste, and inequity. Things are fundamentally unjust and unfair, particularly for the poor and most vulnerable members of society. At worst, you have Somalia.
