This feels like a straw man argument. Who was saying you should not own a set of tools, nice kitchen wares, or exercise equipment? Some people, I’m sure, but not the economists (or psychologists or whatever) who found the “experiences produce more happiness than things” effect, nor most of the people who use this principle to guide their purchases. The idea is that a vacation does more for you than buying a new car instead of a used one (i.e., that this applies to purchases made with disposable income/for fun), not that you should eschew pots and pans in favor of purchasing restaurant experiences. Further, I think most people who generally prefer experiences to things acknowledge that acquiring thoughtfully chosen objects can be a very good idea.
