Your example implicitly means that you do agree someone needs to be made liable for the child through 'obligatory supervision' - because if you don't do that, you will be accountable.
You say 'as long as parents do not violate'. Indeed, as long as you do what is required to ensure nothing goes wrong ("bonus pater familias"), but an accident still happens, then society/German Law accepts no one is liable.
Your argument seems to point more to: How do you define someone as liable and how do you enforce it?
