I very well may be wrong, but if so you are not aware of how, and I will need to find someone else to explain it to me. I’ve been interested for a while in having a serious debate with someone that understands and advocates for the position you claim to have- but if you understood it you would be able to meaningfully defend it rather than using dismissive statements with no technical substance.

The specifics of an entire situation- including the stakes, and how well resourced the adversary is likely to be- affect how you engineer a real world hardened system that isn’t just an academic example- because different security measures have different tradeoffs.
