Short answer: if it could it would already be.

First, no one wants to move away from the "real" thing. The alternatives are there and there, even things line NOSTR where you own your own identity and not a server.

Then, and most importantly, the fact that users do not make the rules is part of the appeal of twitter, even if users themselves do not recognize it. It forces the most dissenting people together on the same platform. If they had to agree on rules, then either everything would be banned, or islands of incompatible moderation policies would form.
