No, this isn't a counter-argument. You're not speeding up a given instance, you're "merely" running more instances or running larger problems. (In some problems, the sequential portion is roughly constant, independent of the amount of data. So, you can reduce the effect of the sequential portion by increasing the amount of data.) More throughput and larger data are both good things but they're not the same as running a given problem faster.
