I think it all boils down to accountability. Your right to drink yourself silly stops when you start infringing on the rights of other people. You dont have the right to steal to buy booze. You dont have the right to abuse other people. And you dont have the right to drive and injure or kill other people. If you do any of these things then other people are within their rights to take legal action against you.
Maybe us non drinkers do need to intervene more. Maybe the A's need to suffer the consequences more. Who knows. You cant hit bottom if well meaning people keep cushioning your fall.
Instead of us trying to fit into their world. How about making them fit into ours. You can do whatever you want but you cant endanger others.
