That is a recommendation on public health initiatives, not individual consumption.
"When it comes to policy recommendations, it is notable that the authors recommend public health measures to reduce total consumption at a population level, such as “excise taxes on alcohol, controlling the physical availability of alcohol and the hours of sale, and controlling alcohol advertising”. There is no mention of information campaigns or targeting heavy drinkers, which may be less effective ways of reducing average consumption."
The risks they found are actually very small.
"Let’s consider one drink a day (10g, 1.25 UK units) compared to none, for which the authors estimated an extra 4 (918–914) in 100,000 people would experience a (serious) alcohol-related condition.
That means, to experience one extra problem, 25,000 people need to drink 10g alcohol a day for a year, that’s 3,650g a year each.
To put this in perspective, a standard 70cl bottle of gin contains 224 g of alcohol, so 3,650g a year is equivalent to around 16 bottles of gin per person. That’s a total of 400,000 bottles of gin among 25,000 people, being associated with one extra health problem. Which indicates a rather low level of harm in these occasional drinkers."
