It assumes that value = price, which is true at the margin, but false (ie, an underestimate of value) for almost all purchasers.[1] Furthermore, for many software products which are purchased in exactly quantity one (1), this underestimate can be arbitrarily large for *all* purchasers. More important (and this is a mistake that finance experts make all the time when they stray into economics), the policy discussion simply ignores the effect of licensing and pricing on _supply-side_ incentives. But that's what the whole argument is about! (except for the irredeemably greedy on both sides who merely want something for nothing).

Footnotes: [1] The idea underlying the arbitrage model of option pricing (aka Black-Scholes) is that for derivatives of financial assets, it _does_ make sense to assume that the only real good is money[sic], all traders are risk-neutral and monotone in money, and that volatility is objective. Those three assumptions mean that _all_ traders have the same preferences for the option, and if the price is "wrong", the option will be untradable (either everybody wants to sell it, or everybody wants to buy it).
