The metric of per kg of product, while entirely fair, can be a bit misleading when it comes to making high impact decisions in your life. The switching to tea example is a good one to criticize because on this chart coffee is quite high up there, but I consume only 15g of coffee a day, compared to probably close to a kg of meat, egg, and dairy. Eliminating coffee would not be a high climate impact decision.
