Thanks Stephen. You've brought this up before in response to another piece I published on Medium. As you know, my perspectives are decolonial and I do not entertain considerations or strategies that do not facilitate practical decolonisation. I see a few fundamental dissonances in what you propose.
The first is that our colonial world order is not predicated upon morals or sound logic, and would never allow for the incumbent profit structures (based upon economic enslavement of everyone) to be threatened undermined in any way. Many Global South leaders have attempted this and it has consistently ended in assassinations, coups and militarised instability.
The second is that even if such idealised fiscally inclusive and equal systems were to be implemented globally, we would still be operating within a colonial world order, one that is slightly more palatable but no less ecocidal, ethnocidal or epistemicidal. The same One World would be exerted over all of life. Suffice to say that interventions that make a colonial world order more palatable to its peasants and slaves impede rather than support decolonisation.
The third area of dissonance is the assumption that states, banks, or money are relevant constructs in decolonisation. Given the cultural evolution of coloniality and its use of these structures, they are far more likely to uphold than undermine colonial power structures. Wealth is certainly relevant, as is the power to govern/manipulate people and resources, but states, banks and money may not be important or necessary in futures decolonial perspectives may seek to build (or be forced to endure).
I personally therefore tend not to endorse any ideas and interventions related to monetary structures.

Also! Thank you for your writings, I appreciate your perspectives.
