This is an angle I’ve often attacked when trying to argue (unsuccessfully) with a lot of my peers that Amazon is a scumbag big business. Sure, Amazon’s return policy insulates my wallet against getting garbage, but it doesn’t insulate my conscious. I liked Amazon for a long time because it saved me time and lowered my carbon footprint by saving me from having to drive to the store, but when I have to return an item from a third of my orders, usually having to drive to the UPS store for drop off, it really degrades one of the more compelling aspects that got me into the habit in the first place.
Also cheap “good enough” products that don’t have a rigorous design process and carry no warranty are certainly unhealthy for the environment. “Scratching the itch of novelty” as a counter argument is very selfish in my opinion.
