With domains on auto-renewal, unless you are with an incompetent registrar or there is some legal issue, you won’t lose your domain.
I agree that there should be some non-forfeitable right to a permanent personal domain though.

There's tons of exceptional circumstances where people can lose access to their domain. Some TLDs have no grace period at all and it can be fairly easy to lose access. For others it's larger, but even there, it's not that hard to see how people can lose access for one reason or the other.
Are the chances small? Sure. But some are also outside your control and apply "small chance of [..]" to a large enough population and before you know it you're excluding millions of people.
Or in the spaghetti parsing, obviously nobody is going to have swear words in their email. Go ahead and blanket ban all of that. And then @JohnsonAssociates.com gets banned.
I’ve also seen email parsing rules get applied to login screens too. So the valid email rules get updated and suddenly you fail validation trying to log into your already existing account. Ran into this today actually.
So having your own domain might solve some problems but you may still end up needing multiple accounts with devs refusing to use correct parsing rules.
