Irrelevant. And I might point out that welfare people have 100 ways of still getting booze and getting around the law. But every bad law starts with good intentions, and yes, there are some people who would spend every last dime they have on liqueur and drink themselves silly. So IMO, there should simply be a LIMIT on how much alcohol a person buys. But more to the point, as little money welfare people get, I don't see how they can afford to buy much liqueur anyway.
So if that is all the money they have, they are prohibiting sick, poor and disabled people from buying a Coke. Soon after, it will be all sweetened drinks.
Once done, it will be the next step to simply ban snacks, junk food, sweets and stuff from everyone. Big Brother is going to make you eat healthy or die.
They opened the Pandora's box and you walked right in thinking it would only apply to those "other" people!
