So by your logic if there is no UBI suddenly money ceases to exist completely and we can't have price discovery? You are quite the contrarian. That works good for ideology, not regarding the laws of economics so much. Price discovery does not cease to exist just because certain people don't participate in the market.

The fact that you linked this segment of an article as an argument shows me you nor the author have any understanding of the definition or function of price discovery (or perhaps are willfully perverting it).

Price discovery is the method by which producers are signaled the supply and demand of limited resources and therefore are able to price them correctly. Certain portions of people not participating in the market (even if true), do not prevent the mechanism of price discovery of RESOURCES. An individual person or even groups of people's inability to "price signal" as the article puts it is irrelevant to the price discovery mechanism because some one else wants those resources more and they are willing to pay for it. No amount of waving your magic money wand will make producers want to sell resources for less than what they could realistically get.

In short price discovery sets the value and price of resources. With out it there is no reliable way to do so and production is interrupted resulting in over or under supply causing instability and shortages long term, for everyone.

I have read enough of Friedman to know he did not support UBI, and enough of your work to know you hear what you like and discount the rest. That article is more contrarian tripe again jam packed with rhetorical and ideological arguments sprinkled with economic terminology in a sad attempt to give it credence.
