> A physical good (food, clothes) is depletable, and in that way too unlike digital data, which is for all practical purposes undepletable. But if you consider even highly inexpensive physical goods, they have various substantial costs of transportation, inventory, etc. associated to them, and thus they are not truly as fluidly and effortlessly reproducible in the way that digital data is reproducible for zero cost.
Right, that's why I said "not for free but for their low marginal cost." You're hand-waving with the "zero marginal cost" argument without addressing my counter-point. If the fact that something has a marginal cost approaching $0 means you are morally obligated to provide it for a price approaching $0, why is there not a similar moral obligation to provide something that has a marginal cost of $3 for $3?
