Isn't this actually a really common sentiment, though? I've lived in several places where leaving a bike unlocked for 5 minutes, or sloppily locked for an hour, means you're going to lose it.
That doesn't make the theft acceptable, but if a friend borrowed your bike and left it unlocked you'd still get mad at them.
Reshaping society so this stuff doesn't happen is great, but on an inside-view level we treat crime as sort of an inevitable "someone will do it" force.
I don't disagree with you, however I think there are some levels to this concept, e.g. how two different locations would differ if it was: a lost wallet, a somewhat clear opportunity for embezzlement, a bike stopped in front of a coffee shop?
The same kind of stupid person that doesn't realize they live in a ghetto called "The Internet".
What's the problem with these people?
Sarcasm aside, I live in Brazil, ask any Brazilian who stayed on an European country what was the biggest difference: "I could feel safe anytime, without worrying about my stuff".
That really shapes the mind and behaviour of people.
