Absolutely. The current level of service these companies provide is functionally identical to what would have existed 25 years ago. Losing your Apple account would have been a minor annoyance - the relationship involved trivial amounts of money, and wasn’t deeply integrated into anyone’s lives. Even if you lost an email address, losing access to it wouldn’t have locked you out of hundreds of important accounts, and any important accounts would probably be easily updated to a new address with a phone call, and likewise for a few friends. If you got fully locked out forever, it really wasn’t important.
So, we now have the same “who cares, it’s just some dumb online account” level of service with much more critical accounts. Because big tech has scaled users to the 9-10 figure range, while not investing almost anything in customer service. Instead of having thousands of CSRs like the phone company, tech employs a few disempowered call center operators overseas, whose only job is to read FAQ answers at callers and ask them to try restarting their computers.
To say nothing of weaponized account locking.
I shudder to think how vulnerable the current system would be to intentional denial of identity via other parties tripping fraud systems on an account.
Say, while the target was traveling?
