People have been navigating with a compass since ~1300 AD for navigation. Before that I suspect they used celestial navigation, an astrolabe, the sun, knew the route from experience/oral tradition only, or simply became lost. New fangled technology vs others. Of course maps are pretty darn old, too
Before sunscreen or sunglasses? People covered up with clothing..or ignored it and "enjoyed" various types of skin cancer, cataracts and/or premature aging of the skin.
Night time jaunts? Well, people stopped. Or used torches, candles or lanterns. Just ask the ancient Greeks or Chinese.
First aid? Conquered most of the Mediterranean world with it I reckon... About 2000 years ago.
And since they marched ~20 miles a day with 60 lbs of gear, a repair kit was needed.
And shelters, warm clothes fire starting kit,etc ... Well, Ozti thought they were pretty good ~3200 BC.
So, not sure of your point unless you are advocating hiking naked, going without food, and doing away with nearly 5000 years of technology in many cases.
While a valid case can be made for using a compass or not on the AT in three-season hiking, this "And yet somehow humans did without some of these so-called "essentials" for eons" argument is well, not correct.
People have been using the ten essential in one form or another for EONS to use a term from another person.
Warm clothing, extra food, navigation aids, ways to tend to/repair equipment and protection from the elements have been needed for a long, long, long time.
