Morning, these are good

Morning,these are good questions, and I’m afraid the short answer to them is, we’d just have to debate and decide.Longer answer: see, even Von Mises et al. didn’t dispute that we could as a community simply decide what it was we wanted to consume, the basis of the argument of economic calculation rests not on end goods, but intermediates.  To take your bread v. beer example, both are using wheat, and one formula, say, for beer uses 5 parts wheat whilst another uses 3 parts wheat (but uses, say, a synthetic chemical).Our opponents say we wouldn’t be able to choose between the different formulas of beer, and so we couldn’t rationally choose how to allocate our wheat (after all, opting for the synthetic chemical may commit a lot of energy and resources, far outweighing the putative savings of wheat).So, what we need to add is the idea that because information flows freely through the system, we would know the true state of supply and demand (i.e. how much wheat there is, how much demand there is for wheat, and the amount of synthetic substitute available).  After all, that is all the market is meant to do already.  Except where the market measures effective demand marked in money (which is subject to manipulation) we’d have real demand expressed in real units upon which to make our decisions.I hope that answers your question.
