You could just throw an error, freeze services and do whatever "let someone handle this on a case by case basis". It's absurd to suggest that the customer doesn't want to have the option to prevent their spend from growing by multiple orders of magnitude without a human in the loop. Sure maybe deletes are a billable action (also absurd and fake), but having the options to say "hey I can't spend more than X, cut my service if my spend + cleanup would cost more than X" is absolutely doable and something many people would want.
If you think that deleting all data (blob storage, block storage, VM states, caches, etc) is preferable to a surprise bill, then I don't think there's anything we can debate here.
I agree that there isn't anything we can debate here, but it's because you're making straw men. There's a middle ground here between getting charged 4 orders of magnitude more than you expected and having all of your data deleted that you're obtusely refusing to consider.
