"what good do you suggest would come from having roles unfilled?"

At least in part: NotA (binding, as described at the site) removes the finality/fatality of voting for the lesser of two evils (or incompetents). Consider NotA a training device for any and all potential candidates (you have to step up with something other that the tried/tired and true/trite).

In the same way: banning formal political parties forces potential candidates to 'think' and 'consider' rather than simply 'adopt'.

Together: NotA and no-party politics makes for a better grade of candidate and a better grade of voter...certainly: not all the problems get solved but the two together make for one helluva start.

"how would we function if many NOTAs were "winners"?"

How do you function now?

Governance (American) was never meant to be the foundation for an individual citizen's living. Largely: you are meant to be left alone to do what you can and will and like.

"Unlike you, I don't believe there should be no government."

As I've said before: proxyhood (hiring/electing folks to oversee and maintain the American esoteric and physical infrastructure) is preferable to 'governance' (governors directed the governed).
