I don't find the argument that “my vote didn't count” under a given electoral system to be particularly compelling, because, one, I have been a scrutineer at an election before and I remember that we counted all the votes. So it's not as if people are dumping some ballot boxes. That's in a legalistic sense. We've counted all the votes.
The other sense is that “my vote wasn't pivotal in electing somebody”. Guess what? There's one median voter. They're pivotal in electing a member, and the rest of them are either surplus or not.
If you want a system that maximizes votes counting, as in votes going to elect people, then here's the system: Any candidate who gets a vote gets elected. That's the logic, right?
