It's not just 2mg/day; it's 2mg/day/kg of body weight.

So a woman who weighs 110lbs (50kg) would have to drink 50 times that, or 5000 pints in one day to pass the EPA limit.

Obviously most people won't drink that in a year, and this article is fairly useless for limiting itself to the easy-clicks topic of booze versus industrial agriculture chemicals. What I think would be interesting is to look at, across an average diet, what one's total daily glyphosate exposure might be, against any relevant clinical information, but that's more of a research paper than a piece of blog content.
