If Musk woke up one day and decided to turn X into a Nostr based system:

- Issued keys to every user account and allowed users to collect their keys or bring their own

- Signed every message retroactively

- Turned their internal servers into relays so users could collect the now nostr-compliant notes, or post them without being logged in; also for non-X clients to read notes from X relays

- Enabled zap support

But X still:

- Required you to have a user account for the npub notes to be accepted by their relays

- Refused to accept and relay notes that violated their terms and services ie. moderated their relays

- Terminated user accounts if/when a user violated their rules enough times

- Maintained premium subscription tiers that restricted the types of data their relays would handle

What would you think about X, and Elon himself, if this were to be done?

Personally I think it's not an ideal system, but it would be a massive improvement over the current. I also think it might actually be something he could be convinced to do.
