Why have all countries moved away from a traditional economic system? What are the drawbacks to living in such a society?

all countries moved away from a traditional economic system

because

A traditional economy is a system that relies on customs, history, and time-honored beliefs. Tradition guides economic decisions such as production and distribution. Societies with traditional economies depend on agriculture, fishing, hunting, gathering, or some combination of them. They use barter instead of money.

Everyone has different beliefs so eventually, peoples different beliefs could lead to conflict.

Instead, it emphasizes the trading and bartering of products and services that enable participants to subsist in a specific region, community and/or culture. Largely, traditional economies are a way of life in underdeveloped countries that rely more on old-fashioned economic models like farming or hunting than on newer-age modes like industry and technology.
