Asset-Backed Mutual Credit Systems for various Assets?

I am very interested in how we apply the concept of asset-backed mutual credit currencies or HoloFuel to any other assets?
I understand how HoloFuel is backed by the ability to redeem for computer power through this asset. For this, a tool for standardization was used by creating an artificial computing quantity: “Computing Units”.
But how can we apply this to other assets that cannot be measured in such a standardized way, e.g. in the field of social innovation or human systems or relationships?
