Yes, I think one difference between the US and european countries is the likelihood that the potential thief has a pickup truck. In addition, far more bikes in Europe are used for short utility trips to the market where a relatively insecure lock is still likely to be adequate.
I've been using a very flimsy cable lock for my grocery and other market trips a few times a week and haven't had a bike stolen in over 30 years. It would be easy to cut but does guard against the guy who carries no tools but might be tempted to hop on an unlocked bike and ride off.
