Well, again, in principle, NFTs can be used to represent ownership of anything. The current crop of NFTs I find just as silly and worthless as you do. However, I will note that even the current stuff is no more worthless than, e.g. a piece of paper autographed by a celebrity. What NFTs are right now is the digital equivalent of an autograph. I think buying a hat autographed by LeBron James is stupid, but obviously a lot of people disagree.
However, theoretically, you could tokenize other assets, like real estate, or intellectual property, and then trade them in a more liquid, global manner than is currently possible. The NFT ecosystem is one of the least developed parts of crypto, though.
If you want an example of tokenized value, just look at stablecoins. Stablecoins are literally tokenized dollars. They allow you to self-custody large amounts of, what is effectively digital cash. That is something you couldn't do before. If you didn't trust banks, you either had to store physical dollars in your home, which is extremely dangerous for a number of reasons, or you had to suck it up and trust them anyway. Crypto gives you a third option.
