> What kind of stupid person would think that we could have a cooperative, functional society where I can just be careless with my bike, right?
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.
