Yes, That is just re-stating what the author wrote, without providing any clarifying information.
> You seem to have interpreted that as saying that the financial system should answer that problem for society as a whole.
Maybe yes that is a maximalist interpretation; what is the alternative interpretation (it doesn't seem to be present in the author's text)?
> move away from min-sum towards sum-product (which often works an order of magnitude better) by perhaps implementing basic income. Etc. Etc.
Referencing 'basic income' here seems like a whole society problem to me, which has nothing to do with the technical implementation financial payment gateways, no?
Myself, I don't think that you can untangle (even in your mind) the mess that is the market (financial system, really) from the mess that is the government. They're called "voting dollars" for a reason.
I prefer to just refer to the whole big mess as "The System".
As for downvotes, I don't think they add any value to the site except to encourage groupthink, and you're better off ignoring them. Or take them as a hint that you might be on to something! :)
