I remember learning most of this when I was in scouts, even though I’ll admit I can’t say I remember most of it.

I definitely remember at summer camp once having to take a bunch of wood found within the forest and making a makeshift shelter and for one night having to sleep in it. All for the wilderness survival badge.

The skills you listed are definitely skills people should know just in case they are ever out in an area without cell signal. Although, really, everyone should know basic first aid since even just a little bit of first aid before a first responder comes can be the difference between life and death.
