Imagine you needing something to live, that's abundantly available that wasn't even created by someone else and in order to get it you have to give up something on exchange.
The concept of currency in exchange for goods is the epitome of selfishness
I fail to see your point, or understand your position.
What alternative are you proposing?
There is an option to the way the majority of modern society lives.
An individual can acquire land build their own shelter. On this land they can farm and raise livestock. The individual can also make their own clothing and tools. They can collect rain/ground water and treat it to make potable.
The issue is that most people cannot afford to do this, or choose simply to engage in the greater economy, which is an evolution of barter.
Instead of walking around with a wheel barrel of corn or soybeans, you carry the monetary equivalent (i.e. currency).
Humans have traded good and services for currency (and other things) for thousands of years. How else would you get medical treatment if you weren’t a doctor, or have a home built if you weren’t a carpenter/mason?
Even some animals have been observed to help/benefit each other in the wild.
I’m sure if animals weren’t wild, they would have created their own barter/currency economy too.
But you know; their wild animals and whatnot
