Your proof is flawed, of course.  It assumes the election method would
allow one to "change ballots one by one until the outcome changes".
Such gross manipulations are not permitted by the rules of any
election method.  The rules grant to the voter a single vote, and that
is all.

The challenge is to describe how the use of that vote could affect the
outcome of the election, or of anything else in the objective world.
How exactly could it?

You know that it cannot.  Earlier you wrote, 'The only genuinely
meaningful thing is "who won the election?"'  I agree that matters.
But if the election method grants to the individual voter no influence
over that outcome, then either:

  a) What the voter thinks is of no importance; or

  b) The election method is flawed.

We cannot dismiss both of these.  One of them must be true.
