No. Security through obscurity is bad security, but it’s still an additional layer. And since there’s literally no way to 100% ensure that a machine is being controlled by a human, there’s literally no other way except saying “fuck it” and not doing any security at all.
Sounds like you’re categorically defining everything someone does without being forced as “want”. But who is the “you” that wanted to do it if you’re not conscious of that want? Do I breathe while in a coma because I want to? Do I stop breathing because I want to? Or does my low-level biology force me in those cases?
