Yes, collectively. Notice your usage of the plural.
> Every one of the million of votes for the winner matters just as much as the vote for the loser.
This is not the argument you think it is. How do the votes for the loser matter? The loser still lost, despite those votes. There's no consolation prize for 2nd place.
> You are influencing the outcome exactly as much as every other person in line.
Agreed.
> Individually? Negligible.
Exactly.
> But in aggregate, that’s an election.
Also agreed.
The votes matter in the aggreggate. However, I as an individual voter have no influence over the aggregate, or the outcome. Other voters do what they want, not what I want. My vote doesn't change their vote.
I didn't say there was no reason to vote. I'm just saying that it's a bit irrational to vote strategically, as if your vote will determine the outcome. People have been convinced that they have to hold their noses and vote for someone they dislike in order to stop someone they dislike more. That's mass irrationality, and how we always end up with people we dislike. And what did it get the individual voters? Tens of millions of people vote for someone they dislike and still lose. They lose the election and their souls.
