It's obvious. Predicting target selection needs to take the attacker's goal into account.
Of course, not all goals are the same, so one should never use that as an excuse to be lax about security. You may be safe due to a lack of malicious security cracker interest in you today, but tomorrow some other malicious security cracker might come along who has different goals -- or maybe a way to make exploiting your security weaknesses "cheaper" so that suddenly your piss-poor password is so easy to crack that your relatively low target worth is still profitable. Automation works wonders for such things, and automation is what computers do.
The insight that (often average) value determines the most tasty targets is descriptive, and not prescriptive. Just as we should be unpredictable when establishing our defenses, we should realize that malicious security crackers will aim to be unpredictable when planning their own strategies. Secure yourself to the reasonable best of your ability, or you might be the first target in a new attack strategy.
