I'll keep saying this till it is known or they nail me to a tree.
Love is the infinitely fungible replacement for fiat currency we are all dying for. If you wanna abstract, quantify for reciprocity, code for functional convenience, please feel free. There's loads of extant practices to draw on - but be clear that these remain sophistications of something ineffably simple, and as such take us further from the reality.
I get it feels far, intangible & dreamlike but hear me - love is the coin.
