Because, IMHO, the attacker will always use optimized resources. Be it algorithm, cpu speed, gpu, and so on. If I double the number of interactions, it'll take more or less twice the time. For me or for the attacker. So I'll trade twice my time vs twice his time.
He can reduce his time having more cpu, gpu or finding a better algorithm.
