I'd agree with this statement only because you have the word debt in it, as debt is fundamental to any reciprocity and division of labor which results in temporal displacement of an individuals production and consumption (like farming), individual must be able give and receive debt from the rest of society to make that work.
But Usury is separate from Debt, it is a parasitic layer placed on top of debt. It is to Debt what co-dependency is to marriage. I argue that Usury can be eliminated from Debt with Demurrage and this is the best strategy to adopt.
There has to be an illusion of usury, else the 3% will buy feudal (middle ages) armies instead of loans (because they are selfish and ignorant/denial of the fact that capital can't grow exponentially forever). So we need to be clever about how we do it, so that only those who are large enough (the 0.01%) to control the nation-state (soon to be NWO) armies are thwarted, so we retain those 3% who want to buy bonds. Demurrage might be one way perhaps.
If we can remove the public-backstop from loans and remove insurance (that ends up as public-backstop), then they can loan at higher interest than the debasement/demurrage and still they will not grow exponentially forever, because they will pay for their failures in lending to those who can't repay.
Thus in my opinion, the key is removing the ability for the collective to tax and confiscate. That is the only way to end the public backstop and force the selfish hoarders to be subject to the free market.
This is why anonymity is the most important feature in my opinion. But this will only be realistic for the new virtual economy. Yet I expect that to be the main economy now or for sure by 2033 when a recent Oxford study predicts 45% of all current jobs will have been replaced by automation.
This is why I make a point about prosperity has always been facilitated by small government, not by lack of debasement.
