“Good outcomes” is a bit vague, depends on ideological preferences, and is hard to measure even when we can agree on criteria.
In my opinion the purpose of elections is to make the political system beholden, responsive, and accountable to the populace; to give the political system legitimacy so that it will be popularly supported; and to guarantee peaceful transitions of power and general political stability.
Those goals are undermined when a small number of powerful people can intimidate, cajole, or trick the public into voting how they prefer (usually against the interests of members of the public, and the nation’s interests in general). For this reason, I believe in constraints on campaign financing, election-season advertising, and believe that free, fair, and accessible elections should be a political priority in my country, alongside robust public education with instruction in civics and critical thinking, and a healthy independent media ecosystem.
I have no idea what “the inherent moral virtue of voting your heart” means. Feel free to vote for Robin Williams if you want, but realize that in most countries (including the USA) write-in votes for dead Americans are invalid.

I have no idea who you’re responding to, or what your point is. Nobody in this thread ever said anything about an “ironclad one-man-one-vote system”.
