Tokenization and ownership are huge. Ecosystems like Stacks (https://www.stacks.co/explore/discover-apps) have hundreds of Web3 apps already running and providing value.
The value provided by Web3 is simple: now you can program property and ownership on the web.
This changes banking, finance, publishing, social media, etc. It's a huge change because users can take their data across platforms and avoid lock in. Imagine a single social profile that works across platforms (one single profile for Facebook, Twitter, Insta, etc). The possibilities are endless.
I suggest you keep digging in and make up your own mind. Don't let dismissive one liners dissuade you from learning.
Disclosure: I'm a founder of Web3 protocol called Bitfari.
