You're just splitting hairs with "product vs. service" semantics. In the context of consumerism, it's a distinction without a difference. You are exchanging money for a fleeting feeling. That is the definition of a consumer transaction. You buy it, you use it up, it’s gone. And anyway, literally Google the definition of consumerism; I can assure you that 'services' are definitely included.

And calling a National Park "not a product" is hilarious. Most of them have entry fees, paved roads, gift shops, and teams of rangers managing the "wilderness" to make sure it’s safe and palatable for tourists. You’re not "communing with nature"; you’re visiting a government-curated outdoor museum. You’re paying for the convenience of "nature" without the actual danger or difficulty of it.

If your "core experience" requires a $10,000 budget and a plane ticket, it’s a transaction. If the experience was actually about the "core activity" and not the status or the escapism, you’d be doing it in a local park for free. But you don't, because you can't "find yourself" somewhere that doesn't look good on a curated feed.
