The blockchain prevents double spending without a trusted party--that's its only TECHNOLOGICAL solution.
Where you "are going wrong" (your words--not mine) is not appreciating the value of what SOCIAL solutions can from that, and refusing to accept that these subsequent solutions may be valuable to others for purely non-technical reasons.

SOCIAL USE CASE #1: Cryptocurrency
If you're privileged enough to live your whole life without ever being denied access to any degree of financial services, I'm happy for you. However, Satoshi created cryptocurrency at a time when SOCIAL trust in traditional money networks was at its absolute lowest--this context is so important. Cryptocurrency (built on blockchains) offer global financial networks which anybody to participate in, and you are free to form a opinion around how valuable that is to you personally.
SOCIAL USE CASE #2: Permission-less Smart Contracts
If you have a digital payment network wherein anyone can transact, why not create programmable flows around that economic activity? Decentralized financial applications--savings accounts, payment channels, compounding interest, asset swaps, escrow--were all the lowest hanging fruit and so they came first because the network protocol they've been built upon includes a monetary asset natively.
Back in the Web1 days, there was an application called GameSpy. The service provided a way to find a list of community-owned gaming servers that hosted multiplayer sessions for various PC games. Technically speaking, it was the epitome of what the Internet was capable of and it failed because there was no viable monetization strategy for either the middleware or the server hosts that didn't involve centralizing the platform. A web3 version would survive with decentralized coordination, could stream payments to gaming servers, reward players for playing on the platform, and would make a good case for a DAO to provide upkeep of the middleware layer.
SOCIAL USE CASE #3: NFTs
Our lives continue to move towards fully digital experiences, and NFTs are key to commemorating moments in the metaverse.
To be clear: a NFT is a single number (ID index) sitting in a 256-bit address space, which is recorded to belong to some cryptographic data that you keep secret. It MAY have a visual representation you can find with a URL, but that is not a requirement.
