It is absolutely right, but just as absolutely not how most people think, nor how bank accounts are presented to people. In fact, it's considered "foolish" not to store money in a bank account (and, in many cases, it is), but there's also this small chance this kind of thing can happen, but it's never talked about normally – therefore, out of sight, out of mind. It's unfair to blame people for blaming the banks on this, because the banks get a disproportionate benefit from this kind of system, and most people in modern society have no choice but to rely on banking systems. Again, a person avoiding banking systems is scrutinized as backwards and ignorant, but then folks turn around and shame people for not being aware of how the banks truly work. It may not be a secret, but it's far from common knowledge.
