NFT's aren't just digital art; digital art is just an easy implementation of NFT's. DAO's are a decentralized usecase. Centralized entities issuing NFT's redeemable for services at a future point in time is another category. For example, Nike issuing a NFT which can be redeemed for a limited edition shoe rather then selling the shoe online directly, having it be bought up by bots and resold on the 3rd party market. Nike gets a cut of the resale value every time the NFT is resold at minimal effort; they don't even have to build/host the marketplace. Consumers get a limited edition shoe shipped to them directly from the manufacturer with worry about middlemen or authenticity. To your point, people already trust Nike (and many other companies) to send them products.
Do the decentralized "maxi's" like that nike example, probably not. But they don't really get a say whether it exists or not. Everyone is so quick to declare web3 100% dead or 100% going to take over the world. If this was pre social media, nobody would know about web3. The value would be orders of magnitude lower and you'd probably only find out about it once there were "useful products" or never at all if it's a complete failure. But that's not the world we live in anymore.
That’s why they copied the concept a second time with NFTs: it’s a bit awkward to just keep trading fictional currencies for other fictional currencies. Now, you can trade something real: fictional ownership of fictional “art”.
