Society using currency based on people?

Currency used to be linked to precious metals and other physical things of high intrinsic value, then from 1948 after the Bretton-Woods convention countries were almost pushed to 'drop' physically-backed currency to move to fiat currencies.

Funny though that countries like the USA which run one of the biggest fiat currency systems also hoard gold like no tomorrow because secretly that's the backup should the global financial system(s) as we know then today collapse.

The current push to shift towards blockchain-based CBDC's is an example of how the commoditisation of money is changing.

It'd be interesting to see money linked to people/population. In a way we've had an attempt at that via the UN/WHO trying to forcibly reduce the world population through the Convid Plandemic (supposed by the global elite and Big Pharma), but that failed.
