They could do what TikTok does and require you to have x number of followers from your videos before allowing live streaming, but then you just make a market for sockpuppet followers.

People really under-value the credentials for such things and I think it's part of the same problem as when streamers who aren't used to this life yet forget about privacy considerations and end up with a phone number or worse home address known to fans.

If you have a meaningful Youtube income, you need to spend some of your next Youtube check on say two Security Keys. If you like them, buy some more for everything else, but since Youtube is your income, step one lock Youtube with Security Keys.

Once that's required, errors of judgement possible through limited understanding or sleep deprivation cease to be a problem. Baby didn't sleep properly all week, some idiot screwed up your banking, and now Youtube keeps sending emails. You get another stupid Youtube email or at least you think so and either

1. You give Bad Guys your password and maybe OTP, so they steal the account and maybe in 5-10 days you and your fans can seize back control, meanwhile it's used to run scams

OR

2. Even sleep-deprived, confused and bewildered you will not post your physical Security Keys to Some Russian Guy's PO Box, Somewhere else, 12345. Your account remains in your hands because without that physical object they can't get in.

Integrity, mainly. Elon is not an honest person and he will use any power at his disposal arbitrarily to silence people he dislikes when he feels like it.

The most absurd example of all is the very recent case where Elon pretended to be a pro gamer and got caught. A streamer called Asmongold covered the topic on his stream, which triggered Elon to arbitrarily remove Asmongold's verified checkmark and remove his gaming badge. Considering the low stakes of this matter I find the actions ridiculous and don't trust Elon with having basically admin access to the platform at all.

I've also heard plenty of horror stories about the ruthless way the engineering in X is currently done, often carelessly breaking stuff. However I have to point out that the service is and has been far far more stable than the "haters" have predicted back when Elon took over and fired all those people.
