Exactly! This is my big critique about Web 3 — what can it actually do that we couldn't do already?
The new things people propose as Web 3 use cases, e.g. interoperable game items, simply aren't practical. That's why they don't exist already — not because they require blockchain to build.
I've heard people argue that big tech social media silos will be replaced by decentralized Web 3 social media, but why would they be? We already have decentralized social media. The reason Mastodon can't compete with Twitter isn't because it needs blockchain; it's because Twitter has all the users and all the money, and that's because centralization is just more profitable. It boils down to economics, not technology.
And we briefly had interoperable text chat with XMPP until the big players dropped support for it. The protocol already existed, it worked for a while, and then companies decided it wasn't in their interests to stick with it and the interoperable textaverse collapsed back into silos.
