There are over 200 million voters.

A thought experiment about an individual choice is not even close to applicable to the choice facing a single voter since in that thought experiment not-choosing is the same as making the default choice whilst in a vote not-chosing is leaving the choice to all other voters.

The use of this though experiment as a metaphor for the choice facing individual American voters is downright deceitful and propagandistic, self-servingly so since it's being used to try and boost the chances of one side.
