Not to criticize you in any way, but the article is not about a rich person shopping at thrift stores and not at upmarket stores. The article is about a person not buying stuff beyond the bare essentials. Quite a different thing.
I can actually relate to that. I am neither as rich as he is nor as frugal, but I don’t enjoy shopping and I tend to save a bit of my salary every month, simply because there is nothing I want to buy. I don’t relate to the experience of “finding a scarf at 1/10th the Nordstrom price”, because I simply don’t need a scarf and would not consider buying one. I routinely leave coupons at checkout because there is nothing there that tempts me, ever, at any price. I rarely go to thrift stores or boutique stores as I don’t want any of what they sell (I sometimes buy lighters at thrift stores, when the old one is empty).
Being frugal is not buying cheaper stuff, it is buying less stuff.
