This hyperbole is extreme, and unnecessary. If your life depends on the ability to simulate a fake user on a phone, there are more significant problems than a lack of operating system features, and a general failure to defend in depth.

This is a fully general argument against any single thing your life might depend on: seat belts, defibrillators, bulletproof vests, etc.

If the only thing protecting you from getting shot to death is a bulletproof vest, clearly a lot has already gone very wrong, and you're likely to die today anyway. But that kind of thinking is exactly what leads to a failure to defend in depth.
