All value is explanatory, that is, even if it has "intrinsic value" like carbohydrates in ATP in a cell, it is still knowledge instantiated for a resilient purpose (eg to power a cell to replicate its knowledge).

As explanations change, value changes, so anything can be a currency at the level of the individual--in this way, at least for conscious minds, a public monopoly on money is, while possible, morally wrong. It's a form of Marxism.

There's already been a solution the problem of state monopoly on symbolic abstractions for value (money), that started with Bitcoin and has been growing a new global economy since 2009.
