In economics this is often referred to as a "sterile asset". Buffet called it an "unprodcutive asset". The terms "Zero Coupon" or "Non Yielding Asset" might also apply. You should be able to google any of them to learn more about why they're not good for the economy or for the 'investor'.

The TLDR being that the money exchanged for that useless rock is now wasted. It could have been used to provide genuine economic value, instead it was used to participate in another silly, wasteful, "greater fool" game.
