The problem is that you will always need to have a method of carrying around more than a given amount of 'value' in order to exchange 'value'.
As soon as you have more than a few people, and have hunger, food, protection, housing, etc...as soon as you have those things in an environment of many people as individuals, you will need this method of value variability... and transaction.
This is inescapable.
Money is an issue yes.
However, WHO and WHAT controls money has always been the core issue at hand.
Basically, human social and cultural structure, freedom, -and-... 'cashless societies'..are not compatible. At all.
the only two things I know of that are cashless, are prison, and slavery.
