It really doesn't have to be, and setting things up as adversarial is counter-productive. Pretending that you're "balancing" two competing alternatives when they may not even be opposed is a problem, it gets you C++ std::span, a type which was standardized to be pointlessly dangerous because hey, surely if it's less safe that will make it faster right? [Morgan Freeman's Voice: But it was not faster]

I would love to hear about a world where security and productivity are not counter acting forces.

For a start, most people would certainly be more productive if they hadn't had to authenticate themselves.

If you can just create a world for that simple case, then I will rest my case.
