So after a couple years? How is this supposed to be an argument in favor of disposable bags? My reusable ones are just fine after probably at least a decade.

Likewise with the mug; ignoring for a moment that drinking out of a polystyrene cup is disgusting (especially with hot liquids like coffee that one normally uses a mug for), the argument is supposed to be that a mug (a thing that should last a lifetime) is somehow worse than disposable cups because it takes 2-3 years to be better purely on an energy basis?

And the milk bottle: okay, it takes 10 trips to be better; ChatGPT says various sources say a typical bottle lasts 10-30 trips. So it's better. What even is the argument here?

The first two steps are reduce and reuse, after all. Recycle is last.
