My question is indeed what is the point of money whether it is crypto or not. I know a little about bitcoin (proof-of-work: evil for climate so far) and Ethereum (algorithmic contracts, good idea as far as I understand, but still PoW).
The idea of a single source of thruth is neat, and would be useful to avoid lies or fakes in a distributed system.
Money used to be used a means of exchange something of value for the rich that is gold. That by itself shows how dubious money seems, because gold is almost useless in practice. Nowadays, money has mostly only virtual value, because people trust the system, and the people in power somewhat trust each other and they agree through the market on exchange rates.
Anyway, take of instance "carbon budget" of countries, it can be exchanged for money. And they that "carbon budget" can be used to produce new products.
With the money, a low carbon footprint country can bargain to buy some products.
During this exchange the low carbon footprint might have lost value because conditions of the exchanges and the dubbed added value to the products.
It is far fetched, but to me their should be no money, hence probably no crypto-money.
A single-source of truth is helpful, but I am not convinced it is necessary, and is certainly not necessary in a fully cooperative system with no evil.
Thanks including me in the convo.
As implementing them directly in code over the current cyberspace architecture is most of the time impossible, or not efficient (Slow, not scalable, or energy consumption problems, like for blockchains).
Hope I answered you question about code. There is still code, but fundamental brick you play with (the cyberspace architecture and the integrated services is offers in a garanteed way) are different.
