But it adds up when you start having to replace 100 different "it's pretty cheap given how often we use it" items in a year.
And it's not just the cost. It's also the time you commit to being a consumer. Thinking about which one to buy, reading reviews, etc. Some people enjoy being consumers and that's fine. But it takes away from what I want to be doing with my life. I want to buy something once and not have to think about it for a long time.
I don't think people have a frame of reference in their short lives to realize just how much time they spend being consumers and how that doesn't have to be normal.
