So I had a trail of thoughts and I just want to gather and collect them in one place before I forget.
So I already thought about the gift economy as what Christ most likely wanted, which is like anarchocommunism except it's focused on not negotiating with God and giving away what you make without expecting anything in return. Currency need not be necessary for this, but currency can be a gift to those who want to feel rich.
I feel Brazil was already on track with something like this, but I wonder if they thought about switching the direction of exchange for the currency, allowing those who receive or consume something to have a memento or souvenir about what it is that they consumed or received.
I thought about Bitcoin, which is a digital currency, which made me think you can do interesting things with a computer currency, such as make a unique fingerprint for each coin or record a manifest or receipt of what was exchanged and incorporate it in each coin, so that those that receive get an idea of who they got something from and how to reconstruct it. A coin should be able to be constructed from pieces of other coins where you can tally all the receipts of exchange, or simple properties and be able to reconstruct an object simply by looking into the coins you have. Those who hoard the most or consume the most would be very rich, in a sense. They have the most coins and the most responsibility to return favors. They can do this by transforming the objects or goods they receive into a manifest for something new and giving back with that new thing, which would mean they give away their good and the coin they used to create it, or at least a copy.
For consumed goods, you just get a lot of sentimental wealth generated in a fixed place, but the coins carry the ingredients for the consumed good, so you can reconstruct a good.
Then I thought about nature, or at least nature of the world (not of heaven), and atoms and particle-based matter I realized are already somewhat like this currency, where those who consume the most get the most of this matter, and they carry it on their bodies, and the matter used for non-consumable goods gets redirected in its final destination when it's reused to create a new derived good. I don't know about fingerprints and matter, I would think there are less unique things about minute pieces of matter compared to the unique combinations they can be placed into when working with multiple pieces of matter.
But in nature you want to strive away from hoarding matter so you can get to heaven, which is of the spirit.
Anyways, that's all I have for now, but I'll add my thoughts to the thread.
