As SAR is overrun, more people who are stranded in need of help will have to remain stranded in need of help. Some will die. You can't manufacture SAR resources out of thin air. People will eventually learn that they have to take care of themselves. If they don't learn this, they have a much higher likelihood of perishing.

This is the way it has always been, and always will be. SAR is not your primary way to get out of the wilderness. More like your fallback, behind your other fallback, behind another fallback. Actually, I would say that SAR should never be part of your plan. SAR is what comes into play AFTER all your plans and redundancies have failed. You don't plan for SAR specifically.
