While SERE is undoubtedly useful in its context, most of us are not likely to be engaged with hostile forces and need to embrace pragmatic survivalism,which often means we should stay put, conserve energy, and make ourselves as conspicuous as possible, using whatever appurtenances of modern civilization (up to and even including pliers!)we might possess to win out. I'll bet a lot of us even wear shoes when venturing into the wild.
