Even if the author is literally throwing away seasonal items, the environmental trade-off is that they probably purchase far fewer items than the average person.
This. The disincentive to buy anything is constantly present when you live out of a bag. It's an odd way to defeat the rampant consumerism of modern society, but it works.
Yet the author of TFA owns a Macbook, iPad, iPhone and Apple Watch. Sounds more like peak consumerism to me.
Sure. But for the fridge, TV, washing machine and car - which together contain orders of magnitude more embodied carbon and rare minerals than his pocket-sized gadgets - he's condemned by his lifestyle to sharing them with others.
How do you figure? I've had one swimsuit for 5 years & I store it in my dresser. He presumably buys one or more per year.
