Is practically unavoidable in a system like ours; but also not important in this context as there's an implicit "because it was advertised".
One of the ways I'm weird: it's like I have a homunculus of the Marie Kondo meme before I'd even heard of her, telling me I don't really want to buy $thing, or even receive one as a gift, because it won't spark joy.
As a result, my total expenses included rent, food, commuting, utilities, fun… literally everything, all comes to less than €1000/month on average.
Maybe save the indignation for when someone actually advocates for what you're describing? GP didn't say anything in that regard. Can you not handle any small criticism of our current system?
Furthermore everybody buy something.
