The first thing is the why we carry what we do.
We carr because we are planning to cope with a problem.
We are doing it on the basis that we will be alone. And have to cope with the situation on our own.

The pilgrims are traveling an established route.
Because of this there are facilities and amenities along the way.
Also they are not alone. Many others are right there if assistance is needed.

True most people have lost their connection the world around them. But I'll lay odds that the majority here have either not lost it or are trying hard to regain it.

Also true that with knowledge the minimum amount or gear needed can be greatly reduced. Yes with a pocketknife and the proper skill set you can make or scrounge most anything else needed. What most of the gear carried does is buy time. And yes makes things easier and more comfortable.
