I understand your frustration, bitcoins and NFTs are two completely different things. NFTs don't have one fixed value, there are very subjective and the prices we see today might be too much. But who can give the exact value for an NFTs, it can't be 0. Just because you don't believe in them doesn't mean everybody else is also not believing. As long as there is one person on earth willing to pay for it, is there value in the market. Let's look at a different example, skins in online games. Why would anybody pay 50,000 USD for a very rare cosmetic change to an online game? There are no benefits in skins and if you ask my parents or grandparents the value for it would 0. And still there are collectors paying a lot of money for them. You could just install a mod on your PC for free that gives you that skin, only thing is that you don't own it and can't trade it.
