But how do you know which options are stupid? Because they sound stupid to you? Are you confident enough in your powers of detecting stupid that you would base denying people basic rights on it? What gives you that enormous confidence?

The number of people who have an idea what is going on, when we're talking about things like whole US economy, might be surprisingly small. In fact, sometimes I am tempted to think that number is zero. Of course, for me it makes me think maybe we need less government involvement, since a blind giant with a sledgehammer is worse than a blind giant without one, but some people think that means we need to abandon democracy. OK, but unless you are an anarchist, how do you propose to choose the government then? By instituting a series of exams? Chinese tried that, actually. Not sure it worked that spectacularly well. Check it out.
However you miss a points. It's not always or not even often about picking from 2 complex alternatives. It's often a matter of eliminating options that are stupid, illogical, or inconsistent. Doing so often requires basic literacy in the topic involved.
Unfortunately you are right in that disenfranchising a large number of idiots would upend social order even if it was only eliminating those who literally have no idea what is going on.
