The skimmers can use CVV1 and bypass the CVV2 protection in most cases (though that requires them to gen up a fake or fraudulent card and do card present transactions which does add risk for them).
Not so much for them, but the sacrificial mules that go to the (physical) stores (and the mules, at best, know the location to meet their handler, who is not even the person/group responsible for the acquisition of the numbers, but just another middle person).
It costs almost nothing, so a few fraudulent transactions blocked is probably enough. That doesn't change the fact that I believe there have to be more effective methods that wouldn't cost much more.
One of the CC industry "think tanks" (the think tank part of first data; to be honest, I am not sure that part still exists) has proposed various alternatives over the years (including a true non-traceable cash type of CC alternative that was sort of appealing), but the priority of the banks continues to be to insure convenience (with minimal losses for the banks), and almost all the of the alternative involved some sort of additional inconvenience to the customer. If you can come up with a good alternative, there are many many millions to be made. I am not smart enough to be able to come up with a clearly better alternative (other than a personal optimization to remember all the CC numbers, including the CVV2, as you stated you do). Gary
