This is absolutely correct: “A decentralized financial system realigns risk and reward by taking power out of the hands of major institutions and putting it in the hands of the people.” But the simplest way to achieve it is through the organization of (relatively small) cooperative mutual credit clearing exchanges that are networked together into a “worldwide web of exchange” in which credit is locally allocated and controlled but globally useful for making payments. I’ve been refining these prescriptions for 40 years and commercial trade exchanges have proven the workability of credit clearing. The Open Credit Network in the UK is implementing it.

As you yourself admit, there is no such thing as a trustless system. Do we trust people, platform, process, protocols, infrastructure, …?? Does blockchain technology or holochain have a role to play in credit clearing? Perhaps. Maybe you can suggest what that role might be.
