With regards to how skill is more important than technology in these other form of carrying:

A couple years ago I read Survival of the Bark Canoe by John McPhee [0].

There are several discussions of a crooked knife and how it was the "multitool" of craftsman in the northern forests and was used for everything from making canoes to snowshoes.

This led to me learning more about crooked knives and even starting https://crookedknives.com.

One of the most interesting parts about this journey was reading the below quote:

"Skill allows you to do a lot with one tool whereas many tools can be used to replace skill".

e.g. it's hard to learn how to use a crooked knife but once you do learn, it's like having a plane, gouge and carving knife all in one hand.

This article feels very similar in that it probably takes more skill to use a soft bag or basket to carry loads instead of a modern backpack but also gives you a lot more options.
