>the slave is permanently the legal peer of a cardboard box.
You say that as a punishment but I know more than a few slaves that would consider such permanent legal status one of the best rewards possible.

>Master...i get to have the same rights as the cardboard You let me sleep on when im a good girl, Master?

>please i'll do anything, Master! i'll be the worst girl imaginable!
>i'll willingly disobey Your orders, i'll even attack other defenseless slaves!
>please i just don't want to be a human ever again Master!!!

It might have unintended consequences. Probably best to have a legal path for a Master to downgrade their slave should they pass inspection for being this particular kind of crazy.
