Currently models seem to assume that cash flows are primary, and reality is imaginary, which seems a rather odd way to be approaching the problem.

Don't take this the wrong way, but your appeals to "reality" (especially "real value") sound to me like hidden variables in quantum mechanics.

The problem here is not so much that cash flows do not map to physical reality in a straightforward way. The problem is that cash flows are, in all conventional economic models, presumed to map to physical transactions and physical flows of goods in a straightforward way.

In other words, cash flows are important to analyse in their own right, but not the way economists think and not for the reasons economists normally assume.

Not unrelated: my Keynes and the monetarization of economics from July 16th, 2006. In it I quote Keynes' argument to do without real GDP and price level and use only nominal quantities because, after all, cash flows and (more importantly, from Minsky's point of view 50 years later) debt contracts are denominated in money and the nominal, not "real", value is what determines its legal impact (which is what has visible consequences in the real world).

That's 180 degrees away from what's happening here.

The difference is that hidden variables in QM won't kill you if you ignore them.

In economics, political and physical externalities can, and will.

Physical and natural processes don't care about cash flow. And economies are physical first, then moral and political, then abstracted and symbolic, and only then can you think about them financially.

You can only make cash flows primary by writing all of those preceding elements out of a model.

Do you really want to do that?

Do you really claim you can do that? What are you doing blogging when you could be revolutionizing social science?

Do you really claim you can do the economic equivalent?

Why are you blogging when you could get a job with a think tank doing that?

No, I claim it's been/being done by certain economists the mainstream is busy ignoring.
