Is a trade economy necessary?

[Reignforest]

Anthropology is is the study of diverse social systems throughout history.  Through their research we have discovered that humans did not need to have a centralized government or trade economy in order to make complex civilizations. Yet in modern times its nearly impossible to imagine a world without those things. A good book to read on this topic is called "Braiding Sweetgrass " by Robin Kimmer. In her book she describes various native American teachings, such as the honorable harvest,  how language got inverted,  and the idea of a gift economy. I will also attach a video that expands on this idea. This is how I can imagine a Turquoise level civilization using an economy. If anyone has practical methods to apply these techniques,  or if anyone completely disagrees that this is even possible,  I would appreciate your input.
