> alternative is to forgo the debt and trade something of equal value
"equal value" is only a well defined concept when we have shared interests. But when half of us are trying to go to Mars and the other half is trying to prevent the first half from going to Mars so we can instead dedicate those resources to healthcare... when we're fighting over the steering wheel rather than fighting against a common enemy... then we can't usefully coordinate around a single untyped notion of "value". We're just running in circles negating each other's efforts. Our current economy is mostly waste.
New ways of accounting that don't obfuscate conflicts of interest the way that simple debt does will indeed change things.
It may be, but it is one you, the employer, can easily ask during the interview. If a prospective employee doesn't align with your values, you don't have to hire them, and thus won't have to make them any promises to deliver anything that you don't feel comfortable with. This isn't only theoretical. "Cultural fit" is considered by a large swath of employers to be one of the most important aspects of hiring.
I know the typical HN account loves to over-engineer solutions to mundane things, but you really don't have to invent some new type of accounting for this. All you have to do is talk to the people in your life.
That said, banks do provide a useful service for many people. However, that service doesn't magically happen. One has to choose the bank they are comfortable employing. Which, again, requires an interview before accepting a bank to work for you. That is where you can make sure the bank you choose to utilize the services of aligns with your "cultural fit".
Talking to the people in your life is all you need here.
But it requires types of debt which are not exchangable for one another. Whether it's working to take us to Mars or it's working to provide healthcare to our neighbors is something that debt should declare directly, it should not require a duplicate investigation at each transaction.
They got it by you accepting their promise to deliver something of value in the future. If nobody out there is willing to accept their promise of delivering future value, they don't have anything. That's the whole abstraction. It is materialized out of thin air when you agree to accept the promise.
Some new kind of hypothetical accounting system cannot possibly change anything. It will always be a hindsight account of the promise that was made. The only possible change is for you to tackle the promises themselves. Which requires talking to people. That is where the promises are made.
