There's an argument that distributed ledgers enable storage/computation executed by counterparties without trust, but as Diehl notes, people like their money transmitters to come with other guarantees, like "not stealing all the money"--and private+federal banks have *already* developed much more efficient clearinghouses for money exchange. Meanwhile, storage and computation are broadly available as services (e.g. S3/EC2) at vastly lower personal and environmental cost.
