Make an on-chain Twitter clone (e.g., like Bitclout/DeSo), where 3rd parties can't make their own clients for interacting with the same social graph.
Send me a link to the repo and I'll be happy to discuss further and even share any surprises or lessons learned from it.

TBH, it looks like you have a huge axe to grind but don't understand the subject very well. That's why I suggested that you try actually building some things using web3 (which is an eth library)!
It will give you a better mental model of how it works. That will definitely improve your ability to write about web3. Imagining hypothetical apps falls far short of just building a prototype.
Thinking through a topic has a type signature. The required type is "example scenario of your point". You are making points that are vacuous, points that have no example scenarios. It's a problem that can be caught in type checking.
