You're describing the function of money.
What's the significant difference?
Really? Once again, credits are not used in transactions. You do not need credits to obtain anything whatsoever. They are a quantificaton of your productivity and consumption. Transparent and observable to everyone else. I am not describing a monetary system.
You are awarded credit when you provide goods or services.
You are awarded debit when you consume goods or services.
I don't know how else to explain this.
The idea is you will be put off from running up a huge debit record. Because everyone else will know that you're a leech and a drain.
Others will strive to obtain a higher credit, so they can consume more goods and services, without running up a high debit rating.
Others will simply consume little and produce little.
Once again. You don't need credit to buy anything and debits are not debts.
I am not surprised a free market liberal is struggling with this. With respect.
Currency or money be it fiat or no fiat, is a token of recognised value, that can be exchanged for goods and services. Transactionally. This is not that. This is egalitarianism and collective ownership, with a transparent record for each individuals economic activity.
