...what disciplinary options are open to parents then?
Confiscating the phone? Grounding? Witholding pocket money? Removing electronics? Using the "punishment" phone?
Surely they are examples of controlling or degrading treatment so, by that definition, abusive? What would you advocate as suitable method?
They are not controlling or degrading if the parent has clearly announced the rule and the reason behind it, and the child can predict what is to happen if this reasonable rule is broken.
They are controlling and degrading and abusive if the parent invents a new infraction and punishes it in a way that is not predictable or expected and/or in a way that is disproportionate to the infraction.
When the parent does that he sets himself up as a despot, ruling in an arbitrary way, causing the child to always be wary of the parent's mood (so many have tried to excuse the H on the basis of 'last straw' or 'bad day') instead of developing respect for the rules. Ruling in an arbitrary way is controlling and abusive.
In this case the H destroyed the phone in a fit of rage after the child smirked, not because of beer that was stolen. This was a new, unannounced infraction, and a disproportionate and unexpected response. It was violent, it would cause the DS to watch dad's mood in future, and it was abusive.
The 'watching dad's mood' style of parenting is not leading by example.
It establishes the principle that might is right, which is a dangerous principle to establish when a teenage boy might grow a few inches bigger than you and become a good deal fitter and stronger than you by age 17-18.
(Better than any of your suggestions and better than any transgression/consequence model for teens is a conversation about what is going on in everyone's life when two parties have been getting on each others' nerves for a while, and in particular when alcohol is being drunk it is important to establish what is going on apart from what has been taken from the fridge. You don't establish the sort of rapport and trust necessary for that by going ballistic as the H did here).
