I see this is answered in Section 2.7: "Altering the reward scheme must include careful analysis of the resulting market equilibria. For instance, if the currency is too inflationary, then attackers may benefit from adding large amounts of “dummy data” that they can easily reproduce without incurring the cost of storage (e.g., the outputs of a pseudorandom function for which they know the secret key), and thereby gain a net advantage in the challenge reward system over the long term."
