> We simply don't know how to build a system like that.
Yes, but ten years ago, we also simply didn't know how to build systems like the ones we have today! There's been tremendous progress! Now billions of dollars are funding bright people to look for ways to build other kinds of systems.
"We don't know how to do it" is the security-through-obscurity argument. If you have a security mindset, it's not enough to hope that nobody finds the vulnerability. You need to show why they certainly will not succeed even with a determined search.
