The fundamental problem of something like web3 is that is totally unrealistic. Imagine someone "posting" something that should be kept private. Can you go back and delete it? No, because the blockchain is immutable, you can try to hide it but it will still be there. Think of porn revenge videos, it would be a nightmare.
Another example: I recall a videogame on blockchain that had tons of issues patching it self, again because blockchain is immutable.
Also, web3 would really bring democracy to authoritarian states? A country like China with 1.3 billions of people 100% would not improve its democracy situation. That's a lot of people.
Last but not least, almost nobody really cares how web is implemented as far they can browse to their favourite porn site or facebook page or blog or something else.
