Scuttlebutt has been awesome for me to see that a social network can be completely hosted by it’s users.
I think Holochain and Ceptr are here to help us evolve how we work together and do our accounting.
What I love about Holochain's pattern is that it essentially provides a fully distributed, immutable and peer-to-peer crypto accounting framework for barter transactions/sharing work and resources. It does not focus on creating and managing artificially scarce coins (as is the case in the current financial system, and also in Blockchain). It is trying to show us that we are using Industrial Age tools (interest-bearing-debt national currencies), and that instead we could focus on creating peer-to-peer Information Age currencies .
Holochain's pattern enables communities to make their own judgements on what value something holds and how they want to account for it. It allows us to build that into a flow language - a currency. This means instead of using a fiat 'medium of exchange' backed by US imperialism and it's military might/control  - we create, redeem and destroy currencies based on asset-backed mutual-credit principles that mimic the way Mother Nature works. I think I read somewhere that today over 90% of money in the money system is speculative, and interest-bearing monopoly debt-money has no roots in the real world.
An example of a mutual credit currency could be a currency for seats on a train. When I buy a ticket, my ticket is tied to a certain seat on the train. If I went to Mars, my ticket would be worthless. The ticket is only valuable because the ticket is tied to the train system - to one of the seats available. This makes it asset-backed. Another example would be farmers being able to pre-sell their produce locally, without going through expensive middlemen. They can create currencies that represent their produce (the asset).
The MetaCurrency Project is bringing us a into a world where we have more agency when interacting with the world, using evolve-able peer to peer protocols that can be forked and re-forked, again and again, to better meet the needs of it's users.
They are giving us the tools to see the world with new eyes, and to allow multiple perspectives - instead of one rigid, centrally enforced truth.
Moving towards using mutual credit systems, together with reputation currencies (imagine your ratings on Uber, eBay etc. was hosted by your peer-to-peer community), allows you to build trust together in a way, un-intermediated or hindered by a corporate app and UI. These reputation currencies already exist, yet are contained and held hostage by our current paradigm. Other examples of reputation currencies I can think of are ‘FairTrade’ or ‘Organic’ labeling.
Holochain is BitTorrent + Git + Cryptographic Signatures + Peer Validation + Gossip  - making it agent centric instead of data centric. It is not anymore about the database in the middle, but about the relationships between peers and their balances/interactions, and the agreements we make together on what actions we are allowed to take in our different apps and networks. Together we can see and improve the app logic and I can bridge between my apps, as I now have complete control over my own data .
HoloREA is a project that is using Holochain to build a modular, cooperative and transparent economic supply chain framework. It uses the Resource Event Agent accounting model to enable users to steward and follow flows of economic actions. These relationships are today tightly controlled in corporations. HoloREA aims to create a cooperative web of interactive flows of people, actions and resources.
Essentially, the vision is to reclaim The Commons and give us better tools to steward the world together more peacefully and compassionately.
If you’re interested in this paradigm, a few keywords I've found useful: Protocol / Open Cooperativism (currently we have Platform / Surveillance Capitalism), mutual credit, myth of barter, buddhist economics, social darwinism.
I also like the work of Elinor Ostrom, Bernard Lietaer, David Graeber, Douglas Rushkoff (Life Inc.), Charles Eisenstein, E.F. Schumacher, Silvia Federici, Mariana Mazzucato and Anand Giridharadas.

 “Nixon floated the dollar in order to pay for the cost of a war in which, during the period of 1970–1972 alone, he ordered more than four million tons of explosives and incendiaries dropped on cities and villages across Indochina—causing one senator to dub him “the greatest bomber of all time.”7 The debt crisis was a direct result of the need to pay for the bombs, or, to be more precise, the vast military infrastructure required to deliver them. This was what was causing such an enormous strain on the U.S. gold reserves. Many hold that by floating the dollar, Nixon converted the U.S. currency into pure “fiat money”—mere pieces of paper, intrinsically worthless, that were treated as money only because the United States government insisted that they should be. In that case, one could well argue that U.S. military power was now the only thing backing up the currency. In a certain sense this is true, but the notion of “fiat money” assumes that money really “was” gold in the first place. Really we are dealing with another variation of credit money.” — David Graeber: ‘Debt: The First 5000 Years’
What if I don't want a train ticket? What if I want to sell my widget-coin for some brussel-sprouts-coin. Now I can't go to any farmer because he's only got carrot-coin or broccoli-coin, I have to find the brussel sprouts farmer-and not only that, but the brussel sprouts farmer who wants to buy widgets.
And if you say "nonsense, you can exchange any coin for any other coin", how is that different from what we have now?
The MetaCurrency Projects’ Holochain is the next generation P2P no-middle-man accounting system which open sources and decentralizes the rules around money creation and usage. It allows us to evolve the rules together and build mutual credit, interoperable, open and unencloseable carrier’ currencies. Currencies are backed by real world commodities, leading to a rich network of flows between a community.
Your comparison shows me that you might not yet have had the privilege of critically exploring the underlying patterns and stories that have made Industrial Age money the tool it is today. For me ‘The Future of Money’ by Bernard Lietaer, and David Graeber’s ‘Debt: The First 5000 Years’ are very paradigm shifting books and helped me to challenge the underlying stories of economics that I believed. These stories stopped me from seeing a more beautiful future.
