Today, there are various different idea’s for how to operate the economy without using Money. You have the Gift Economy, Voluntaryism, Contributionism, Sharing Economy, etc. All of these are simply different types of ideas for the same basic Economical Model - Indirect and Transient Exchange. The difference is mostly in semantics.
This world has been enslaved through Money for at least 6000 years. We have come completely full circle from the Ancient Sumerian form of Money and Economy. We have evolved through the Gold Standard, Barter and Trade and other such forms of Systems of Exchange, and today, we use pretty much the exact same system that was originally invented by the Sumerians 6000 years ago. We call it Fiat Currency. The only missing variable is that we don’t back it by anything of value, but that’s about to change along with some other things.
