Yes,
The SAR team I worked with for a few years was all volunteer. The best thing we ever got for searches was the awsome meals from the local county sheriff's "chuck wagon".
I never expected to get paid but what I am proposing is when someone goes "out of their way" to get in a SAR situation they should expect to reimburse their rescuers for their rescue. This would ensure that there would be funding for future SARs. Out of the way means BC skiers/ riders, climbers, mountaineers, ww kayakers and rafters etc.
As a climber I expect myself to be self sufficient 98% of the time but if it really hits the fan I would have no problem with being expected to pay something for them coming and getting me.
