If nobody ever stole anything, I'd wholeheartedly support that. In fact, I'm willing to shell out 5 times the regular cost for a bike that would never ever be stolen wherever I leave it.
Finding places to park and lock and worry about it not getting stolen is just way too much.
Relevant: I've owned 4 $1000+ bike over the past 10 years, one of which is stolen right outside home, another is almost stolen (moved then found after a frantic search).
cars are stolen much less frequently than bikes. if your car does get stolen, you're pretty likely to get it back, although you may have to pay for some repairs. if your bike gets stolen, you'll probably never see it again.
