:Your incorrect assumption was basically everything you posted about commodity as you clearly have no idea what the word meant and made arguments based on that failure. Failed to answer points about how replacing money with anything would help in any way. Brought up guns in the same sentence as foodstuffs based on your assertion they were both commodities, when they arent. Failing to give any actual reason whatsoever for linking those things together even in the broken way you attempted. Unless your intention was to say all commodities are bad cos guns are bad and guns are commodities. Which is wrong in at least 3 ways on its own. Before then going on to ramble off some figures about military spending which bore no relevance.
A commodity is, in the first place, an object out side us, a thing that by it' properties satisfies human wants of some sort or another. The nature of such wants, weather, for instance, they spring from the stomach or from fancy, makes no difference.
