I have heard the same "causes passivity" argument applied to the concept of requiring personal locater beacons (PLBs) as well. So, in my humble opinion, why not just apply the concepts to prevent PLB abuse here as well.

When a climber may be in trouble, try to contact the climber to find out exactly what the climber's situation is. If contact is unable to be made and the climber is rescued, simply fine their butts into oblivion if their rescue situation was inappropriate. Nothing like a hit to the wallet to get people to take things seriously. After all, it's not like SAR couldn't use the money!

When the system works out the way it was intended, praise it. When the system is abused, abuse the abuser.
