Yes, that's why they spent a vast amount of resources and money on the V-2. Whoops, wait, that was effort spent on a militarily useless program. (At least the V-1 program was cheap in comparison, if also militarily pointless except perhaps as a political pressure diversion.)
While the V-1 was useless from a military standpoint in terms of whatever they hit, one could argue they were useful in the sense that they forced the Allies to devote considerable resources to shoot them down. Also air attacks against the launch sites were costly as they were heavily defended by flak batteries.
