The government came to us and said, "We want to reduce alcohol abuse, especially binge drinking, because treating alcohol-related illness is getting expensive. Here is some money so that you can write us an advisory report telling us the best way to do this."

And, behold, three of our best researchers got on the job, and did deliver up to the government the best report that could be produced, given the evidence available. (They also made it clear that the evidence available wasn't actually that good, as any scientist should do in the circumstances.) And the report suggested unto the government that the best way to go about what they wanted to do would be to increase the price of alcoholic drinks by x%, and set a minimum legal price for various types of drink. The available evidence suggested that this would discourage binge drinkers, but not cause too much pain to those who drink sensibly.

And the government said, "We're not doing that."

And so it goes.
