What money's actual job is
Observation
Money is described as one thing but performs three roles — exchange, account, store of value — and the three are increasingly served by different instruments.
Narrative
Money is money. One thing, one definition, one debate.
Alternative View
Arguments about inflation, crypto and central bank policy often talk past each other because each side privileges a different one of the three functions.
Unknowns
Can the three functions be cleanly separated at scale? What breaks when the unit of account inflates faster than wages? Which function do households actually optimise for?
Question
When you say you are 'saving money', which of the three functions are you using?
Why It Matters
Most monetary disagreement dissolves or sharpens once the three functions are separated.
