Except that I didn’t leave the doors open. Someone I trusted with the keys, left them in their safe. Unlocked. So I rather have their whole place burned down and MY keys melted at the same time.
A better example might be a storage unit service that left the front gate unlocked. If someone torches the place to illustrate that they need better security would you be comfortable with that? Isn't there a better approach that we should encourage or is OK to encourage people to destroy things that aren't protected to teach people "lessons"?
(I've mostly lived in the northeastern US)
I live in a small (~20k population) rural technically-city (but... it's a town) where crime is not much of an issue; my car sits unlocked in my driveway and I seldom lock my house -- when I do, it's almost always when I'm at home (alone) -- it's about a feeling of security, not any real risk of a break-in. I've lived this way in this town for many years and have never experienced a robbery. I think it's pretty low risk, not irresponsible.
I've also lived in a larger city. There, I absolutely locked my doors. And I've traveled to tourist-y locations known for pickpockets, and kept an even closer watch on my belongings.
The internet is two orders of magnitude larger than the world's largest city and policing it is exceptionally difficult, since it spans national borders. There will be crime.
I wish this weren't the case. I much prefer living in a safe place where I don't have to worry about locking my doors when I go out. But when crime is common, it's negligent not to protect against it.
