How do you intend to consume if none of the consumers have money anymore? How do you intend to trade if the market is polluted by expensive middlemen and centralized .gov pre-selecting the winners and losers? If the standard of living were better in a non-monetary economy in theory, how come it never works that way in practice? Opportunities require money and power to take advantage of them, without either they will not be lost.
Why wasn't the (first) Great Depression a paradise on earth? No one had jobs or money. New high technology all over the place. So why exactly would the second Great Depression be any better than the first, if its of basically the same form? Even worse, recall the interesting economic hack used to "fix" the first one? All you need is a world war, and for the survivors, its gets better.
