I think the idea is that you have to be beyond that point to go to wet houses. Of course, this just makes it so someone would make it look like they're beyond that point. Instead of breaking their addiction they just have to last long enough to be accepted to a wet house.
"Wet houses"-- subsidized housing for alcoholics (they need to get most of their own money for alcohol, but their other expenses are covered) might actually be a good idea. It's cheaper than trying to get them to stop drinking, arguably kinder than trying to get people to take on a very hard task that they aren't interested in, and leads to less collateral damage than having alcoholics couch-surfing or living on the street.
Utilitarians, what do you think?
