While I agree with you, I also think this line of reasoning is a distraction. If we could prevent people from punching you on the bus by technological means with very little drawback, we would.

It's hard for me to see what is the difference between people who question formalizing best practices in computing and people who disagree with modern car engines and seatbelt laws.

We do these things not because it always makes a difference for one single person all the time but because it the system move in the right direction leading to possibilities we couldn't foresee from the beginning.

Someone who works in "real world" security and always have to weight in the downsides, e.g. the implications of privacy when installing a security camera on a bus, must think we are crazy questioning such low hanging fruit.
